Very well done! I liked the puzzles and the music plus narration. Wasn't brave enough to do that myself, so I opted for using dialogs.
The only thing I'd say is a negative is that the puzzles are kinda "samey", if you know what I mean. It would be cool if their difficulty escalated and added more tricks. I'm sure if you had more time you would have.
All in all very cool!
Please play and rate my game if you haven't! And let me know what you think! Thanks!
