I love this game, it feels remarkably polished and bug-free for a jam game. Two points of critique though.
1: At the falling box puzzle, the box kept toppling over, requiring a reset. It would be nice if it just always stayed upright.
2: After getting the water element, I initially thought the game was done, since I was at a dead end. I almost quit, until I saw a comment about a cloak. It felt a little strange to have to backtrack.
