The bullets and floaty physics are very nice. I really like the simplistic style of the game and getting enemies to fall into the pit was pretty fun. My highscore was 21450 which doesn't fit in one line at the end of the game just FYI. Also not sure if it's intended, but you can shoot bullets out of the air which is pretty cool. The yellow enemies were a bit OP though and I think they can kill the big red enemies in one shot if you line it up right. The music fit perfectly, but I didn't see how the limitation was being used. Very cool game, but I agree you could use heals.
