Semi Secret Software seem to be making a name for themselves as developers of games with great pixel art graphics, fantastic music, and high-score centric gameplay that in the case of Canabalt [$2.99] has kept me coming back for just one more try for the better part of a year now. Gravity Hook HD [$2.99] hit the App Store tonight, and provides much of what I loved about Canabalt, only in a vertical climb instead of a side scrolling run. In the game you play as a lovable little robot with a grappling hook who ascends to, well, wherever he's climbing to, by grabbing on to a randomized series of orbs, reeling himself in, then flinging to the next one. Unlike Canabalt which you could hand to anyone with it running on your phone and say "tap the screen to jump," Gravity Hook HD has a bit of a learning curve as you get used to the physics of the game.

The different orbs you can latch on to have different properties, ranging from the green orbs which you can touch without issue, grey orbs which are chained together and fall if you hold on to them too long, and blue orbs which turn in to bombs and explode if you get near them. You're also able to kick off the wall if you can swing your robot towards one, and mastering wall jumping as well as how to handle the different orb types are all required to get very far in Gravity Hook HD.

Just like Canabalt, Gravity Hook HD is playable in its entirety online for free in any browser with the Flash plugin. We've even embedded it below, just make sure you either have your speakers muted or are in an area where you can play sounds before clicking:

 

Gravity Hook HD is universal, and looks great on both the iPhone and iPad, although I've found myself leaning towards preferring it on the bigger screen. Scores are tracked online via Semi Secret's proprietary system which breaks scores out in to top daily, weekly, and monthly submissions as well as the best scores of all time. Gravity Hook HD translates very well to touch controls, and while you can play the whole game for free with a mouse, it really is a much better experience with your finger.

    Go Adam and Crew! Love all the improvements made to this since the the initial. Is that Arne's art at the beginning?

    Eli....your reviews are becominging increasingly shallow.

    You don't even give HOS2 a paragraph (structurally anyway) & you barely even put anything into this hook game (which by the way is starting to turn into shameless clones of the last one released)

    And still it has more than HOS2. You basically said HOS 1 is the something as HOS 2 minus 1

        Yeah what he said

      Agreed -- please remember your audience. On iphone or iPad, the flash box is just a blank space, which isn't enough information to go on.

      I would not call this a "review," just an announcement.

        Just to add to that, I do like his taste in games, so if he sounds enthusiastic I usually buy the game. But I think he's a terrible reviewer. But whatever, as kong as the site brings good games to my attention I don't care.

      • Eli Hodapp

        The majority of the people who view our site do so on a normal web browser. The entire game is literally playable for free. If what I wrote piques your interest in the slightest, wander over to your computer and give it a try. I don't really see the point in writing an exhaustive review of a game that you can quite literally play in its entirety before deciding whether or not you want to purchase it. If you do, please consider stopping by our user reviews forum here- http://forums.toucharcade.com/forumdisplay.php?f=20

        Well Eli, I think you know a lot more about iDevice games than anyone here because you've played more than we have. I read TA because I enjoy getting reviews and opinions from people who know their onions. I would like a review of this if not to hear that it's lacking scoreboards, or that the sound quality is lacking compared to other games, etc. And what YOU think of the game. :)

  • HelperMonkey

    Looks VERY similar to Timothy Braun's "Ascent."

    • GWGumby

      Yes, not just similar, but nearly identical to Ascent. It's interesting how many Canabalt copies are out there, and now they've gone and copied someone else's game.

      • http://trainyard.ca Matt Rix

        Um, Gravity Hook has been out for a couple years... So it's more likely that Ascent ripped off that :)

    yeah, and this game will get the same support like Canabalt?

    The original flash version of Gravity Hook was released in like 2008. It was a simplified version of this game. There was only one orb type. The developers released the flash version of the updated Gravity Hook in early March- Ascent is a clone of Gravity Hook. I imagine the devs aren't very happy about Ascent which is a blatant rip off of the flash version that was out with enough time to whip up clone artwork and gameplay.

    I'm sure the devs won't make that kind of mistake again with their flash versions of iPhone games.

  • juannacho

    I was absolutely OBSESSED with the original Flash version and played it to death. Whilst I'm loving all the HD gloss and everything I'm currently finding that they've overcomplicated things a bit with wall bouncing and different corridor widths.
    Oh, and those red "touch and die" orbs have WAY unbalanced things! IMHO of course...

    Seriously, screw this game. It's difficult and unintuitive.

      Agreed — way too difficult.

    I'm liking it, but man it's hard to get used to. I can't for the life of me figure out how to do wall jumping or whatever. Sometimes I'll get throw into a corridor with just orbs going straight up, but I'm required to wall jump because the orbs are way too far up and there's no way my hook can reach. I've resorted to looking at some Youtube vids, which has helped me get a little better, but wall jumping is still something of a mystery to me.

  • Sam

    I'm still debating whether or not to buy this one being as I can easily play the flash version for free. Also I find the physics a bit weird and hard to get used to. Does it get easier the more you play it?

    Please reply back to this comment saying whether or not to get it (with reasons if you want). If 3 people reply back saying to get it I will.

    • Axl Lowe

      It's fun, but I find the iDevice version to be slightly less forgiving, as you have to be pretty precise in which orb to select. The flash version will help you out by selecting orbs near where you clicked, but not so much on the iDevice version. I find it to be pretty difficult on my iTouch, but I enjoy it. Wish I could master walljumping though. The ranomized layout makes it hard to keep my momentum when it suddenly throws a long corridor up ahead with only one or two orbs that I can't or can barely reach.
