This was a fun concept! Audio would go a long way in cultivating the spooky/tense vibe, but such is the way of game jams. I can tell you put a lot of work into hiding things, it took me a lot of tries to beat it and I enjoyed the challenge.
I'm happy you enjoyed my game! I completely agree that audio would have made atmosphere much stronger. Unfortunately, I ran out of time so I had to submit it without sound. Thanks for your thoughtful feedback.
