I managed to escape! The pixel art with the limited color palette is great and really adds to the creepy atmosphere. The sounds of the locks were also a good addition. I like how the creature appears behind your character during the second-to-last puzzle.
Unfortunately, the moon phase puzzles went completely over my head. Maybe I'm just dumb, but I ended up brute forcing my way to the end. I think an in-game tutorial would have definitely been helpful!
Overall, nice job!
