Interesting premise with a spooky atmosphere, although the lack of direction just kills the joy.
I fully acknowledge that this is a game jam project, which is difficult to make considering all the limitations and time, of course. Nevertheless, I think the game definitely need direction, at least a simple not explaining what to do with the tapes, why is the ritual up on the second floor and what is going on, overall. Otherwise, the game has no major issues and it plays well, functionally.
Best of luck with the game jam and future updates. Cheers!
