Pretty basic, story feels a bit stretch, mechanics are somewhat arbitrary. However the game is very solid from start to finish, it has every part required for story, tutorial and atmosphere. Graphics is gorgeous (aside from some stock UI elements). Overall it feels like a nice finished game, which is much better than an ambitious unfinished one.
Game deisgn wise, I found myself evading purple light so much that I didn't even see the monster itself, so a player can miss some content on a normal playthrough. Maybe it's better to add jumpscares or scripted encounters to at least show monsters to the player. The difficulty and level design is good, I completed game first try under a little stress, feels perfect for a jam game. Great job, congrats on solo submitting a cool game!
