It runs great in browser, which is already a win for a 3D puzzle game. The key puzzle was definitely my favorite. I love the idea of having an in-game notebook, even if I quickly realized I'm terrible at drawing/writing with a mouse lol.
There are some really cool ideas in here though. Clean design, strong puzzles, and never felt unfair. This is one felt thoughtful all the way through. Also I like how you managed to squeeze The All Mighty 'S' in there lol
