Beautiful game, like others have said the paper art style was a great choice. While it took a second for the directional input to adjust every time you entered a new area, I found that it didn't take away from the core gameplay.
I really enjoyed the time loop mechanic and the puzzles were the right amount of challenging. I think I may have gotten softlocked though which is unfortunate because I wanted to keep playing but the code that you find on one of the sheets of paper doesn't unlock the top door. I wasn't sure if I was missing something, so I tried brute forcing every combination of the 4 symbols on the sheet and nothing worked. Just wanted to let you know about that bug!
Overall thought it was a cool submission!
