I really enjoyed this one! I feel like its tricky to fit a full narrative into such a short jam timeframe but impressively you've stuck the landing. It was very fun trying to piece together the story before it concluded and to exercise my own reasoning with the safe puzzle (I'm not sure if I did it the intended way but I ended up joining the two double-digit numbers I had seen earlier). The game's atmosphere also totally had me in its grasp and I was on edge the entire time (I'm not so great with horror ahaha).
There was a camera bug I faced where it would keep snapping every so often which was quite disorienting and while it added to the haunting vibe - overall it felt like it made the experience worse off.
I'm not quite sure what to suggest for the future jam iterations. You more-or-less have a full narrative package present already. It's possible for you to perhaps add further complexities to the story but it's already pretty good as is. Apologies for not providing better suggestions!
Great work though!
