This is a very interesting and clever game. A pleasant surprise for those who like puzzles and riddles.
The only criticism I would make is the initial menu, the "quit" button doesn't make sense in the browser and causes the game to crash. Furthermore, the menu moving up and down makes it difficult to click, I clicked "quit" by mistake.
The artistic style is not my favorite, but it seems very well done and made with a lot of love. Congratulations on the final result!
