Very beautiful game. Loved the music and art style. Perhaps this comes with a fuller game and demo, but my only comment would be that it would be nice if there was further hints/clues as to how the puzzles we're solving are connected to a narrative.
Answers to, why there is a music pattern written behind a bookshelf, why a bird is delivering a piece of a clock to me, etc. Would love to see a cohesive narrative built around an otherwise very engaging experience. Thanks for sharing!
