There is a good concept here.  The color switching mechnic is cool, but I don't see how it pertains to the theme of the jam.  (It did remind me of Titanfall 2's time switching mission, which could be a cool angle to pitch it at though.) 

I wasn't able to get through many of the levels, largely because some of the controls did not respond in the way I was used to according to my inputs.  Sometimes, for example, I would hit the space bar in a critical moment and the colors wouldn't switch.  Othertimes the character wouldn't respond to things like jumps and wall jumps.

I suggest a fantastic video by Jonas Tyroller about how to tighten up those platformer controls really nicely.  We used a lot of the same methodologies he talks about in our entry, The Dream Wood. (The Title of the Video is "5 Reasons Your Indie Platformer Sucks! (+Easy Fix!)"  I DO NOT intend to say that your game sucked.  It's just the quirky title of an otherwise very helpful video)

This is game is pretty fun to play, nice work! I'm not sure how it fits the theme though and some music would really take your game up a notch
