The colours really hurt my eyes. I guess this is superhot in 2D.

Very cool idea. Also the colors are pretty great most of the time. Plus everything interacts with everything, which is nice! :D

In my opinion the game goes too fast when moving or shooting. You can't dodge bullets anymore once an enemy is too close and you can only fire so fast... That makes it feel a little unfair at times and it also makes dodging the inferior strategy overall. Just standing still and firing as much as you can is the best strat most of the time. That's a small balancing issue in an otherwise great game, though. Good job!

This is tough, but interesting.  Suggestion: what if it had a rewind mechanic, maybe you could shoot a moving object to trigger it. Overall good job.

This is going to be a hit, make it into a full game. By any chance, was this inspired by Braid?

Hey, it was a lot of fun! It's really freaking hard >.< But it makes me want to play more because of that :) Really nice sound effects too!
