I really enjoyed this. While very short, it is one of my favorite games of the jam so far (and this is the 96th game I am reviewing).
The gameplay is very simple, but the central idea is quite original.
The visuals are extremely evocative and the sound is very dramatic and effective at creating a sense of absolute dread. The writing is very solid.
I can honestly say I would have enjoyed twice as many challenges to wade through. Some interpretation to tie the phenomena together would be the icing on the cake.
