Cool game! I'm a fan of puzzles and especially puzzle boxes. I enjoyed solving this one :)
The Cypher Master's Puzzle Box
A downloadable game for Windows and macOS
This is the Cypher Master's Puzzle box, a short game in which a little girl breaks into her Grandfather's study after bed time to play piano, and finds herself locked in. Solve all 6 sides of the puzzle box to escape!
If you require a hint, look at the following link for a short walk through. Please note that I do show the explicit solution to all of the puzzles in this video. Unfortunately due to time constraints the puzzles have not been play tested to their fullest extent so some of them may be quite tricky, but they are all solvable!
