Hey, thank you very much for your comment. I would love to be showcased in GMTK video, but the competition is just packed with great games, so that won't be easy. But I am very greatful that you think so highly about my game.
I'm really glad you didn't have problems with the movement system :)
About difficulty balance I sadly didn't have anyone else playtest the game before I submitted it. The main idea is that levels from start to green telephone are tutorial, and later levels are the true game. Sadly again, I didn't really menage to keep it that way I think, because the level right after green phone is easier and only introduces yellow gate (which to be fair is green in the level's lighting xd). Green Telephone level should teach you about getting the controls back, but I guess from the comments it didn't do it's job :D The level that is supposed to teach you that same color platforms share inputs is the purple "KNOCK KNOCK" room.
I'm starting to think really seriously about expanding the game further I have a lot of ideas that didn't make it to the submission build, and also now I'm getting a lot of great feedback of what I could change/implement. Accismus's code however is a complete mess, for example the game is hardcoded for the 5x5 rooms right now, soo... I would probbably start from scratch if I will decide to take the idea further. I am also thinking about creating a walkthrough for everyone who can't pass the levels right now, and maybe a devlog on itch page so I can explain some of my choices and the narrative (which right now is really open to interpretation :D).
Thank you very much once again for the feedback and kind words. Also about the bug could you tell me in what room it happened? I will note that as something to check.
