At first I was like "What the hell am I playing?" When I started to collect the pages ıthought it was like a Slender Man game. Then I saw the other guy chasing me and realized this is a Slender Man game!
Level is cool, running from an entity in a house filled with random objects. Some object had z-axis fighting, and some are problematic but that's okay for the jam.
Lack of sound is you biggest enemy I think. Even just a little tension music would make this game feel finished.
I collected like 15 pages and then the chaser just got me through 3 meters. Interesting experience.
Also 866 mb? How? You may need to optimize the assets cause it's too much. That's one of the reasonswhy many people don't play. It's hard to download, especiall ysomething with big numbers.
I suggest looking at pacify and slender man on steam. I like the concept, needs to get its own identity.
