Very cool concept. A little too deep for my simple mind (I suck at puzzles) but I recognize a good puzzle game when I see it! lipi summarized my concerns in a previous comment already. Great submission.
Thanks for your feedback !
Don't be too tough on your brain, sometimes while testing I couldn't myself find the anwser ^^
If I extend the game, I'll rise the difficulty slower with maybe a skip level mechanic at a cost
