I can't give a rating sadly, because I did not participate in the game jam, but overall, I really liked the game!
Personally, I'm a big fan of pixel art games and I think it really suits the vibe! The concept is very interesting and fitting for a horror themed game. Of course, given the limitied time to work on this game, it is hard to encorporate a story, but maybe a short intro would have been nice to just give a brief insight of what is going on.
What I personally think was a bit confusing, is the fact that the game automatically starts over without showing a game over screen. This gives the impression that the player did not actually die and is taking something with him from the previous attempt or that his previous attempt is in some way affecting the current one. However, since this does not seem to be the case, encorporating a game over screen would have been good. Also, it would have been nice to at least have the possibility to pause, resume or quit the game - just a regular 'pause' menu.
Overall, I think it's a nice game and definitely has potential to be further developed to incorporate some more creepy enemies (maybe fights :D) and a bit of a story :)
