Really good game. I didn't particularly care for the mechanic of the 3rd world (the purple water was ok, but not the ghosts) as it kinda turned many levels into not really a puzzle game but one of reflexes, which makes it pretty inaccessible, which is a shame as puzzle games is one of the most accessible genres. Especially the boss on 3-7 I found completely inaccessible and I stopped playing there. That said, a remarkable game for being made in 48 hours and I think this could be amazing if you wanted to turn it into a full game and added the ability to skip levels that are too inaccessible. Good job.
