I tried your game. I am sry for the negative review; I almost never do this. But the game is so boring it hurts. huge massive world, with only 1 music track that loops every 15-20 sec. Same assets, only trees over and over again, an empty world, the game is dead of emptiness and some buildings. I played for almost 30 min and only found a couple of papers.
In the future, try to have more complex worlds, like a big forest like in the real Slender Man, and add maybe 1 huge house. A tunnel, some factories, other big buildings, bathrooms, etc... Having different sounds, not just one music that loops, makes you crazy after 5 min.
Good luck
