I suck at this, spent like 50 minutes playing the game and haven't completed it. Still enjoyed playing (you know, I wouldn't spend this time playing a game I don't like)!
I don't have much to add to the other comments honestly. The puzzles appear to have a lot of different solutions thanks to physics, some of them require dexterity, some probably don't. Not sure if it's good or bad, depends on your intentions.
The visuals and audio is great though, excellent job on the game!
