For a game jam project, the game looks promising indeed.
I played a little portion of the game, which I guess is all that the player can do. The atmosphere is superb, very liminal and spooky. The environment design is unique as well, although there was not much indication about what to do and I was able to go up and the "antagonist" did nothing special. Of course, because this is a jam game, I fully understand the development issues, which might occur, but hopefully it gets an update and emerges as a longer experience with a bit more story and menu.
Best of luck with the game jam and future projects. Cheers!
