The art values on this game are great... the gameplay, not so much. You move around in a mecha, shooting enemies with one of 4 guns (the sword and laser have unlimited ammo.) Z fires your weapon, while X cycles through them. You move with the arrow keys andcan pull up a map of the level with Q. The game is set on "easy" by default, and it is indeed pretty easy... if you want a challenge, you'll need to adjust it in the setup menu. Moby Games has a brief review of the game here.
