The amount of polish on this submission is genuinely impressive! The puzzles were engaging and the process of learning how to use the mechanic of toggling platforms was really fun! Playing this game was responsive, and the feedback from collecting keys and completing levels was really well done and made me want to keep playing :D Certain parts were quite tricky to get the hang of. The collision with spikes felt a tiny bit off sometimes and wall jumping was difficult at first.
An amazing submission.
