Awesome game! I liked the creepy atmosphere and strange lighting, as well as the fitting low-poly artwork. It could have used a few jumpscares, though I understand that this is a creepy game, not a horror game. I like the puzzles, however they are very challenging. I have yet to complete it after multiple tries.
Overall, this game is well done (especially for one done during a short game jam like this, and with such a little in-game gameplay to give the player). Nice job!
