Cool concept! After a while you just start recognizing patterns and you get a feel for what the level is telling you to do.
This is probably my only real piece of feedback to this game: It is essentially a puzzle game where you try to untangle paths between similar colored points. But the way it controls is also dependent a bit on your reaction and aiming skills. I think I might have preferred a control scheme where you took a more "turn based" approach to pathing, instead of a real time one.
But maybe that's just me :-) I do think that you have a cool system going. Maybe you could somehow use the rewind mechanic as part of solutions to the puzzles?
Good job in any case. It kept me entertained for a good solid 5 minutes :-)
