Actually really fun! I've enjoyed general game loop, only issue I did experience is that "spam e" does not work for me at all even if I spammed as quick as I could.
Great job! :)
I like the vibe! I think it is a solid start and concept, however there some troubles with technical side. Fullscreen isn't actually full for me, game stays in the corner; book somehow always resets game to the start which doesn't seems to be an expected behavior. I would also suggest make interactive parts somehow obviously interactive.
But very nice game! Multiple endings a neat feature.
It scared me real time :D. Very nice horror theme fitting. Unfortunately web build seems to break time to time (specifically camera movement), I guess nothing can be done with that.
I feel like there just missing an interactive part with the world of the game, there are things on scene but I didn't figure out if there anything to do with them. It would be really nice to have some interactivity, maybe to throw stuff around to mislead the monster.
I also think that it would be nice to add some obvious sound level indicator (not necessarily UI, maybe like sound ways from the player in game).
Overall I think for a game jam it a solid prototype and it would be nice to see a full game later :)
