| (Platform) Your goal is simply to get to the kitty you see right above you, but to do that, you´ll need to collect a whole lot of different powerups and blast through hundreds of aliens. Initially, you can`t even jump, so you might want to find that powerup quickly.
Arrow keys move.
Once you get the powerups, Z (or Y or UP) is jump and X is shoot. C uses rockets.
Super duper top secret keys:
0 = mute
- and + change volume
P to pause and see instructions/powerup list (or just click outside the game window)
R restarts the game
