Wow! Great game! I love how you implemented the black and white constraint, and it worked so well I didn't realize it until the last level! The only thing I would change is the character controller. I found that at the peak of my jump, there seems to be some force applied to the character to send it going down faster. I don't want to make any assumptions, but I assume you just wanted the jump to feel a bit less floaty. My way of fixing this would be to turn up the gravity scale on the character's rigidbody (assuming you use Unity!) and turning up the jump force. Sorry for the long comment, but apart from that one small thing, I genuinely think it is one of the best games submitted so far. Keep up the great work!
Edit: I forgot to mention the amazing feature of flipping the stage! How did you even come up with that?!! It works amazing and it makes for some great puzzles! There's so much more I would comment on but I'll leave it there.
