Excellent game! The use of time-stop for puzzle platforming is splendid, and bullets, lasers, and time-stop feel like they could be used for so many levels!
I would like to report a bug I found twice though. During the level that explains what ESC does, if you change the color, return to the game, pause, change the color back, and unpause, it causes you to launch straight up into the goal. I can't seem to recreate this on any other level though.
