This was a very unexpected and pleasant experience! The mechanics were fun and just before they get repetitive, you add more! Like the ability to whitewash(?) completely flipped the game on it's head. Feedback I would give is to make the collision shapes fully envelope the green platforms (often I just slipped through the very edges) and maybe snap the player to edge of the platform to avoid them falling off trying to move the block.
Overall, engaging and underrated. :)
