This is a short 'metroidvania' platformer (just one large level). 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. Your score is measured in time taken, with a 20 second penalty for getting killed, and a 1 second bonus for each alien you blast.

Super duper top secret keys:
0 = mute
- and + change volume
