I really, really like this entry. Although I do feel it a bit cheaty to have the other color change, I like what your going for with this, alot.
The puzzle of trying to figure out how to flip all levers to open the door using your other selves is a neat concept that can make for some really interesting levels. But I think on a technical level this game is suffering from some glitches.
For one, I found myself only able to play the tutorial and level 1. Going into the portal at the end of level 1 left me in a kaleidoscope textured room I was unable to escape from.
Secondly, it was a bit unclear to me my "other selves" were interacting with the level. I thought the rewind was meant to give you more time in order to escape, I didnt know that I could pull levers with my other selves. A bit more visual clarity (maybe make them blue, like the background?) Would have been very helpful in figuring out this mechanic.
Other than that, if I were to play more of this entry i'd say it was phenomenal. Really good job!
