By default, the game is controlled using swiping gestures, but also includes two different control methods with either arrows on the sides of the screen, or a virtual D-Pad. Gameplay in Frogman is nearly identical to Frogger. You hop from one side of the screen to the other, rescuing helpless civilians, and trying not to get run over.

As you progress farther in the game, the simple traffic patterns slowly get even more complicated, eventually introducing boats, trains, and even platforms over lava. While hopping back and forth you can pick up various powerups, such as one that lets you jump over an obstacle and another that slows everything down. The slow motion powerup becomes particularly vital in later levels.

Here is a brief gameplay video of a preview version, keep in mind that the sounds are not finalized at all. Revolutionary Concepts plans on adding voices, new sound effects, and much more music to the game before its final release:

Frogman should be available very soon, and we've been told that it will be priced "well under $5." An iPad-specific version featuring higher resolution textures is planned and will follow the launch of the iPhone version by about a month. If you too grew up on the well-greased joysticks of Frogger arcade machines, keep an eye out for this game.

Everything you loved about the first iEscaper! is back. The gorgeously-detailed 3D environments, the brutally challenging puzzles, the haunting zen-like soundtrack – all of it. But that doesn’t mean that the winning formula of the first iEscaper! hasn’t undergone some tweaking.

Puzzles are no longer confined to single rooms. You’ll often find a clue or an item in one room that needs to be used in another. This means you’ll need to be considering every room in the castle when you uncover new items and clues. It also means that some backtracking has been added into the mix, but not so much that it feels like a chore. The size of the fortress may feel vast, but you’ll quickly realize when backtracking that any room you need to visit is only a handful of taps away.

Despite the little changes and jaw-dropping environments, what really defines iEscaper! 2 is the difficulty. Some objects are tiny and hard to notice. Some puzzles lack an obvious solution at first glance. If you don’t have the patience for it, iEscaper! 2 is a game that might drive you mad.

The game also suffers from some weak translation, hence the subtitle ‘Castle of the Doom,’ or your pursuit of the ‘Crystal of Dragon.’ Little touches like this almost felt intentional and endearing, but alas, the developer has told us that an update should be arriving any day now to address the problem and improve the English text.

It might have an interesting setting and beautiful scenes, but iEscaper! 2 is all about its challenge. If you’re a veteran of the escape-the-room genre, you’re going to love what’s offered here. If you’re not… consider this a trial by fire.

While there is no Lite for the sequel, the Lite for the original game remains available if you aren't familiar with the genre.

An adventure logic game, Crystal Cave: Lost Treasures challenges the player to exhibit the required ingenuity to move through the game's treacherous environs, pulling off the right moves at the right time in order to find the treasure and move on to the next level. The game's riddle-packed levels span three different graphic scenarios.

See the developer's gameplay video.

With over 100 levels at $0.99, Crystal Cave: Lost Treasures is a great value and should have definite appeal for fans of the classic version, Boulder Dash, or logic puzzlers in general. This one comes highly recommended. Those wanting to try before they buy can grab Crystal Cave Classic Lite [App Store] or the OS X and Windows demo versions.

To mark the release of this new title, Rake in Grass has lowered the price of the original Crystal Cave Classic from $3.99 down to $1.99.

And in further Rake in Grass news, the studio will shortly be releasing has just released a match-three action puzzler known as Phantasia, developed by 300AD.

Phantasia, designed to appeal to gamers of all ages, challenges the user to save an unfortunate group of fairy dwarves imprisoned within colored spheres. Row by row the spheres move down the screen and it's up to the player to destroy the spheres and free the dwarves by firing his or her spheres at two or more advancing spheres of the same color.

The game offers both an Arcade and an Adventure mode and delivers over 30 levels of gameplay.

See the studio's gameplay video.

Mobile developer Croquis has just released Castle Fantasy [link], a side-scrolling hack-'n'-slash platformer, through the App Store.

Castle Fantasy is something of a "2.25D" affair in that it consists mainly of 2D character and backdrop illustrations (more than 2000 of them, according to the developer) and is played on a 2D plane, but there is a sense of depth conveyed through varying platform heights and, at times, foreground parallax scrolling fields. But, more simply and to the point, it's a very lovely game that's well-illustrated and smoothly animated.

Gameplay involves moving your character through the game's levels — there are four chapters, each with seven stages — while collecting gems for power-ups, slashing enemies, and jumping from ledge to ledge. Some of the ghoulish enemies are much more difficult than others, with greater endurance and range weapons. The occasional boss enemy is encountered along the way, as well. At the medium difficulty setting, it's quite a challenging experience. Some of the challenge, however, comes from the game's controls…

Your character is controlled by way of onscreen buttons. Movement is handled via left / right buttons at the lower left (I find it best to treat these as a "slider") while jumps and attacks (both short- and long-range) are triggered by a button cluster at the lower right, with a sort-of fatality button bottom-center. In first playing the game, the controls feel a bit cluttered, but extended play does bring a good deal of familiarity which helps the situation. Still, when the action gets intense, I find myself occasionally attacking when I want to jump or failing to move in the desired direction. It's definitely not a deal breaker, and there's only so far a developer can go in the controls in a game like this on the iPhone, but it's a little frustrating. Also, it takes a little while to get accustomed to the ideal distance and pacing of short-range attacks in order to not get clobbered constantly while delivering your blows. Skill in this regard brings much more success.

Happily, those daunted by the above paragraph can give the game a try before reaching for the wallet, as there's a free, lite version available as well [App Store].

See the developer's gameplay video for a look at the action.

Our forum readers are highly enjoying the game, some calling it one of the best action platformers in the App Store. After the learning curve, there's definitely some intense action to be found in Castle Fantasy. We recommend everyone at least give the light version a try.

One of the first highly successful games in the App Store was Majic Jungle's Chopper [App Store], a side-scrolling aerial shooter that's an adaptation of his original Mac release. The game has seen well over one million downloads since its release and is a pretty fun time on your iPod or iPod touch.

We spent some highly enjoyable face time with Dave Frampton, the man behind Majic Jungle, at MWSF '09 and WWDC '09. As such, I've been following him on Twitter and have long been seeing the occasional tweet about the progress of his upcoming sequel, Chopper 2. Yesterday I pinged Dave and demanded a solid update on this title that we've been quite anxious to see. Happily, with minimal threats, he agreed to give us the latest details and an exclusive set of screenshots of the in-progress title, as well.

Chopper 2 is a complete re-write, with full 3D graphics, numerous different landscapes and a realistic Chipmunk based physics system. It still retains the classic side-scrolling shooter gameplay, however. The control system in the game has been completely overhauled, allowing for touch based aim control independent of the tilt based flight control. There's also the option to use a touch based flight control method with a virtual D-pad.

Chopper 2 has eight different enemies with unique weapons and AI. There are also allies in some missions who will help by firing at the enemy. Some enemies fire homing missiles, and some fire multiple missiles in rapid succession. The missions themselves are also much more diverse than in the original Chopper. In one mission, you and your allies defend a base while a long line of enemies attack from both sides. In another mission you pick up a bomb disposal expert, take him to disarm a bomb in an office tower, and defend his position from attacking enemies until he's done. Sometimes you have to kill a certain enemy but are free to ignore others, and sometimes you must not kill any enemies. There is limited ammo and a new health meter that allows you to take a certain number of hits before you die. Most missions have a base or two where you can regain health and/or ammo, but there is a time bonus you'll be sacrificing to do so.

Chopper 2 will be utilizing the OpenFeint network for online scores, with a high score tracked for each of the 12 locations. Each location has three missions, and there will be three difficulties to play through. This makes for a total of 36 missions in each difficulty setting. The progression structure is non-linear, with a map based system where you unlock new locations and missions to choose between.

The story is not yet complete but, similar to the original Chopper, there is instructional story dialog before each mission. However, Dave tells us that Chopper 2 has a unique and impressive way of delivering this dialog, which makes the story a lot more engaging. We'll hear more about that as the title approaches release.

If all this isn't enough to pique your interest, Dave is also working on an iPad version of the game that will be part of the single-app release — one version for both iPhone and iPad. Having planned to release a Mac version of Chopper 2 following the iPhone release, Dave has had high resolution graphics at the ready all along. He indicates that the work involved in fully utilizing the enhanced features of the iPad is fairly minor and feels that it makes little sense to charge gamers again for it.

Dave was kind enough to provide us with an early iPad simulator screenshot of Chopper 2 in action. The shot doesn't feature all of the graphics of the final iPad version, but it does give some idea of what the device's extra screen real estate offers.

Chopper 2 is not too far from completion, but Dave indicates it won't make the April 3 iPad release. There's no solid release estimate right now, as the developer wants to make sure the game is fully ready in all respects before it lands in the App Store, but he tells us it's coming along quite nicely. Price is yet to be solidly determined, but Dave indicates that it will fall somewhere below $5. Stay tuned for more details on Chopper 2 as we get them.

As it turns out, with the roguelike formula held firmly in mind, Kevin's been busy at work on a new iPhone game. Yesterday, in our forums, Kevin announced his forthcoming title Spirit Hunter Mineko: Demon's Reach.

Spirit Hunter Mineko: Demon's Reach is a roguelike / dungeon crawler with a bit of a backstory. The game centers around Mineko, an average teenage girl who enjoys exploration, spelunking, and sparring with tough monsters. Stubborn, short-tempered, and rebellious, Mineko lives with her family in a secluded mountaintop village. She is a Spirit Hunter, trained from a young age in the art of channeling her spirit to perform magical feats. And while she demonstrates great skill, she is still treated like a child by her village. However, Mineko's chance to prove herself has just arrived.

One dark night a vicious storm kicks up, tearing through the valley below and whistling through the peaks that she calls home. Upon waking the next day, Mineko and every last member of the village are amazed to see that this was no ordinary storm! Down in the valley that previously contained nothing but dense forest, a huge castle has materialized… apparently from thin air! Its sinister appearance, as though an enormous evil hand was stretching out of the earth towards some unseen desire, immediately earns it the name "Demons Reach".

The village council decides to send a scout into the valley to investigate and, in a move that infuriates Mineko, her brother is chosen for the task. Not one to mope about the house, Mineko grabs up her dagger and crossbow, opens the hidden door in the floor of her bedroom, and it's off to high adventure she goes.

Spirit Hunter Mineko, while a dungeon crawler like Rogue Touch, is rather more similar to some of the iconic SNES and Gameboy Advance adventures of the past. It features a unique world with monsters, gameplay mechanics, and graphics not inspired by any existing roguelike. Unlike the much more graphically simple Rogue Touch, the new title is an OpenGL ES-based affair featuring smooth-scrolling travel through the game's various levels. As the development of the title progresses, detailed animations and particle effects will come into play, as well. The developer likens his vision of the completed title to Shiren the Wanderer for the DS.

Kevin has just posted an early video of the game that serves as more of a "tech demo" of the game system as it stands currently than a demonstration of any meaningful gameplay.

The developer tells us that, while the early video demonstrates his line-of-sight algorithm, he plans to finesse the system with a smooth-shadow effect before release. He also indicates that the onscreen mini-map, in the final game, will start small and slowly fill out as you explore the randomly-generated levels. And, while the video shows only the game's dungeon environments, there are currently four different environments / tilesets planned for the release version.

We're told that there's much left to do in this title before it's ready for the App Store, but, remembering Rogue Touch, we're rather confident that the end result will be worth the wait. Stay tuned for more on ChronoSoft's Spirit Hunter Mineko: Demon's Reach down the road.

In Blast Off, you control a tiny rocket ship blasting through space rescuing astronauts. Touching the screen tilts your ship in that direction and fires your rocket, usually sending you off that way. Your enemy in the game is gravity, and the game is over when you crash– Numerous celestial bodies are scattered across each level, each which have a different effect on your ships trajectory.

As you blast through space, you have to keep an eye on your air and fuel gauges. Air serves as the timer for the levels, and fuel is consumed as you touch the screen to let off rocket burns. Once you get a feel for how the ship performs in space, it won't take long for you to sling shot around planets and use gravity to your advantage to really only need to fire your rocket for minor course changes.

Two different game modes are included, endless mode where you need to rescue as many astronauts as possible while picking up power ups to refuel and refill your air supply. Classic mode consists of 45 levels with multiple difficulties where players must collect as many astronauts on screen as possible then make their way to the warpgate without running out of air or fuel. Both game modes are a lot of fun, although I've found myself preferring endless mode.

Online scores and achievements are tracked via OpenFeint, and Halfbrick has even released the game's soundtrack as a free download on their site. If you've had fun with these kinds of gravity puzzle games in the past, Blast Off is really worth a look.

Flick Bowling 2 is controlled using simple touch gestures, and once you get the hang of it, flicking your finger across the screen to bowl works really well. Unlike the original where you applied spin to the ball by swiping across the screen, your entire shot is done in one flicking gesture. To throw the ball straight you flick straight up, to curve it in a particular direction, you simply curve your finger flick. It works surprisingly well.

Another new feature in the sequel is the addition of a story mode. Playing as either Jen or Jim, you'll warp through time (somewhat like Bill & Ted's Excellent Adventure) to face off in bowling matches against famous figures in history who also have similarly themed bowling alleys while you make your way to the ultimate bowling showdown with the evil Baron Von Schtopwatch. The game itself even admits the plot makes no sense. Aside from story mode, you can also play regular bowling games as well as a quick three frame game.

Here is a video of me doing poorly against Cleopatra:

One of the most interesting things about Flick Bowling 2 is how Freeverse is pricing it. While the original Flick Bowling launched at $4.99, the sequel will come in two flavors: A completely free ad-supported version, and a paid ads-free version. The only differences between the two games is advertising, and the paid version also comes with multiplayer. Both games will also come with DLC packs for customizing your bowling balls, as well as an additional Helen of Troy level.

Freeverse is shooting for launching Flick Bowling 2 on the 23rd, and I really recommend keeping an eye out for it, especially if in-game ads don't bother you. The bowling control mechanic is fun, the new physics engine is a massive improvement over the original, and the time traveling premise of the game, which is beyond ridiculous, is hard to not enjoy.

In many ways Aftermath is the zombie shooter I've been waiting for.

You find yourself walking the streets at night of a zombie infestation, trying to fight your way out of the city. It's dark and raining. The entire scene is dark with the exception of your flashlight. You move around frantically trying to take out the incoming zombies when a flash of lighting reveals a horde of them right behind you.

The mood of the game really is perfect. The lighting effects, 3d engine and sound come together to give Aftermath a great feel. Your character is controlled by two thumb pads, but not in the traditional dual-stick format. Left is movement while the right one lets you turn left/right. Meanwhile, firing at zombies is automatic when you point at them with your flashlight. While this may sound awkward, it works quite well and makes the game feel a bit more realistic and frantic as you must be facing your opponents to fire at them.

Another aspect of the game that really stood out was the large city map in which the levels take place. There are blind alleys, cars, and buildings. You need to navigate your way around parts of the city to make your way through the level goals. This is a refreshing change from other dual stick shooters such as Alive 4 Ever which have all taken place in small square-shaped arenas. In Aftermath, you really feel like you are getting lost in the city.

Check out the video for the gameplay:

The game, however, only comes with an 8 level story mode and a final survival mode, but is integrated with OpenFeint for high score achievements.

While there is some replay value in the existing story levels to improve your score (and, of course, the survival mode), the main criticism about the game is this relatively short level structure. The early levels can go by really quickly and leave you wanting for more.

Still, it's hard to find too much fault in the game at only $0.99 when other games launch with much less. If you're looking for an atmospheric zombie shooter, this one's an easy recommendation.
