A nice idea, reminds me of a calm version of fury of furries (if anybody actually remembers that game!)

Really fun and creative game. Combining recolor and rewind mechanics has made some great puzzles. I loved the platforming too, it was pretty smooth but I had some small issues:
-As others mentioned the character is too slow, I was holding shift all the time. I don't know if it's intended or not but almost for all jumps I had to sprint because otherwise I just couldn't jump far enough.
-Some platforms were too close to the ceiling (for example the ones near the first red color change)
-The vertical platforms caused some jittering which can be easily fixed if you make the player become a child of that platform once they come in contact. (sorry if you already knew it but it was a problem I had too so I thought it could be helpful to you)

Great job overall!

Looks pretty cool and gives me chills. Music fits perfect. But i don't know what to do about the first wall which i am supposed to break. I don't know how

nice game

Great job! The neon scheme on black background is beautiful. The player's movement is a little slow, but I understand this is a chill game, so that makes sense. It did take me quite a while to figure out the first key, but it's a puzzle game so thinking is part of it. One thing I noticed is that you can jump further by sprinting then jump. Perhaps that could be an addition to the tutorial area? 

Wow, what a well polished game! I enjoyed that the rewind ability wasn't some odd mechanic added in or you had to fight against. Instead, it added to the experience of not having to go back through a section or seeing yourself go back to the beginning was satisfying. My one complaint is how slow the character moves left and right. Excellent first game for a game jam!

Fun game, i love the graphics and the sound design plus the meteoroid-vainia ish aspects really gave me a sense of progression. im impresed with the amount you got done during the jam ( :
