good puzzles
Liked the idea of hiding things everywhere to wait until the right time, loved the clock puzzle. A lot of times it is about finding where the items are and there are few things that appear odd like the shaping. I think the key shaping would be nicer to be done by player then automatic.
I'm kinda dislike the idea of retrying from zero, though it is fine for this one since it is easy to go back to that location and the retry button is on the game.
