I enjoyed the puzzles and difficulty, reminds me of some oldschool flash games. However I'm not a fan of the player movement. It feels slippery and imprecise, and the jump height made it hard to go up "stairs" that had things above them. That makes the game less fun because it doesn't make the puzzles harder to think about, it just makes trying possible solutions more annoying. Also, I had to zoom the page out to get the game to fit on my screen.
