The controls are simple and work like every other side scrolling shoot 'em up. The left and right arrows obviously make you move left or right and the red button fires. A jet pack, however, gives you the ability to hover for as long as your fuel meter allows. This lets you collect moon rocks (for money) and fly over the aliens themselves. There are three weapons in game, and each can be upgraded multiple times. Killing aliens and picking up floating rocks gives you money to buy upgrades. Additional bonus items are provided in randomly scattered crates throughout the levels. Finally, the crate labeled with the letter "R" starts rush mode, where the music ramps up and swarms of aliens come from both sides.
Three difficulty modes are included, as well as a story mode that is said to take around two hours to complete as well as an endless endurance mode.
Here's our gameplay video showing the tutorial and the first two levels:
The production value of the package is great as evidenced in the video above, which makes it feel like a very good value at only $0.99. The game play, itself, falls back to a side scrolling survival shooter with a few nice touches. Early impressions are being collected in our forums.
