very cool! it does have some similarities to my game, but still very different! i like the mix of shooter gameplay and procedural levels. i feel like the auto-aiming makes the game a bit less of a challenge; i think it would be more enjoyable to have to aim. love the screenshake and the level transitions! i was a little unsure what was good/bad at first. i would have liked a little more visual feedback when you get hit (like a color flash on screen). lots of fun though!
ps-- i couldn't get fullscreen to work. pressing enter (even while holding alt) just shoots.
