Really cool game! I actually ended up playing through the whole thing even though I didn't expect to! The puzzles felt elaborate and really well designed,. It's clear a lot of thought went into them! The intricacy of the puzzles also had a really nice curve, starting off simple and then becoming much harder to guess what to do next. I loved getting those "ah ha" moments and understanding when/why I needed to loop back in time, really great stuff!
My only nitpick is movement could be a bit faster, especially since you'll end up replaying quite a few dialogues and such. Also would be nice to have a smoother diagonal movement, but it didn't hurt the experience much. Otherwise, great game and congrats on the submission!
