Very solid submission overall. The art, while relatively simple, contributes to the overall atmosphere of the game, and everything fits well together without any assets standing out negatively when compared to the rest.
The gameplay is fun and reminds me quite a bit of Killer Frequency, with the whole navigating somebody else through their horror experience. The sleeping option in the cabin also helps with disarming the player's suspicions regarding the story, as one would expect that the game spans several days because of it.
The plot twist sneaks up quite slowly on the player, and while it's easy to figure it out beforehand, at that point, it's pretty much too late already, and you're just left wondering if you could have done something differently.
I think the most area for improvement is in the sound design as there isn't particularly much beyond the base atmospheric sounds, which do set the mood quite well. Just some more key sounds at the big moments would have really helped there, though I suppose there probably wasn't enough time left to take care of those.
