Nice and simple arcade game, the graphics aren't too detailed but I don't mind that. The character controls do feel really slippery, so it makes it easy to run into enemies while trying to get a square of your color. I didn't find myself using the second rewind mechanic too much (rewinding time), I think having short bursts of enemies where the player is either forced to rewind and then position themselves, or if they're close enough, just position themselves would really help make use of that mechanic. Nice work!
