Interesting concept with the colour changing affecting the environment. Movement was a little clunky in terms of jumping and wall holding, jump momentum seemed to be lost if you hit a ledge and wall jumping was unpredictable. Not sure if this was just my PC or the game but the colour changes caused the whole game to freeze which disrupted the flow and caused me to fall down quite a few times. Noticed a couple small things such as sometimes not moving along with the platform you're on and the player continues to move the box even if it falls below or above them. Otherwise very creative idea and quite fun, puzzles were a good level of challenge.
