Cool, you should add a bomb to clear the screen all that rewinding can be frustrating.

Did you know polybius was made by the guy who created mario Im not gonna try to spell it.

It's an interesting idea (once you get it), but you get swarmed by enemies far too easily and it becomes impossible to progress. I would make the AI more forgiving. Right now there are too many cases where you get stuck in a corner reversing the same bit of time over and over with no way to get out.

WTF it's impossibble to progress do far that you halucinate

My eyes hurt so much, epic.
