**SPOILERS, PLAY THE GAME FIRST**
Okay, there are several things I can say about this one.
First of all, holy f*ck. Did not expect horror. The first two jumpscares are genius. The presentation is S tier, I almost cannot believe you did this alone in three days. Felt really tense and immersed all the way through, especially with the limited lighting and the ambient sounds.
Secondly, the downwards door in the first room is such a tease. Could've been a second ending, especially with how you could walk back to the previous rooms (which you shouldn't be able to do unless there is more stuff to do in the prior rooms). Is there only one ending? I liked that ending, but that door really threw me off with how it was implemented.
Third, the submission itself. I will not be able to give this game a good review with a good taste in my mouth, because the way it was uploaded broke the most essential rule of a game jam: no submissions after the deadline. You should submit it in time and double check whether your upload was correct or not. I'm really sorry, but you'll get it right next time!
Small afternote: it was weird how from the WASD keys only A and D worked, but the arrow keys worked fine. I guess it was a small error, it didn't make the game any less playable.
Overall, I'm really bummed about the failed submission, because this is one of the best games I've played this entire jam. Amazing work, and I'm really looking forward to your work in the future. (Also, you were able to make me sit through a horror game, huge props, I'm a scaredy cat :D )
