I feel like something might be a bit buggy about the game? Every level, I'd shoot the correct objects, but it wouldn't proceed to the next level. I'd have to kill myself by shooting the wrong things and restart the level. Once I did, I could proceed to the next level. I'd have to do this every level in order to proceed. Did I just mess it up?
Anyway, that mild confusion aside, I did enjoy it for what it was, and the sound design was pretty satisfying.
