Loved it even though i constantly felt like an idiot when i solved the puzzles and saw realised how long they took me.
The atmosphere was really unsettling and palpable in this game and i loved that you tackled the horror from a less on the nose direction. It felt moody and queitly unsettling in a way that jump scares dont deliver. I felt like it was exploring something and making me think (not just about the puzzles). I dont really know what conclusions i've come to yet but Im really impressed a game jam game has sat with me like this at all.
I saw in another comment you used a custom engine with three.js !? this entry would be impressive if you have used Unity, but to achieve this all in a limited time in Three js is amazing, congrats.
Great job, really solid entry and definitly something i will be pondering for the rest of the night.
