Multiple different puzzles, that's really cool! I really like the music too, but the sound effects felt a little odd sometimes, like when I was holding the stones it kept spamming the sound effect, not sure if it was intended. Going fullscreen didn't seem to work as I thought too, the screen just kinda got filled with trees instead of having the sprites actually become bigger. These puzzle/mini game compilation type of games can be super fun, I think your puzzles were really good there, simple and effective, although I think they could be a little bit harder but that's just me. Good job!
