I love the mechanic of the time traveling and the puzzles that opens! The sound design is absolutely phenomenal, and I love how it adds the horns when you're playing them (the music is so good). My only gripes would be that the physics seem a bit wonky (probably that the player is a box collision instead of a capsule) and that the interact button is a hold instead of toggle. Other than that, great job on the game! It's fantastic.
