Im working on the following recommendations:

Player gameplay motor (very slow climbing rocks colliders and hills)

Adjusting pages height 

Remaking Slenderman IA and IA Bake (Keeps stucking!)

Changing some weird action keys!!

Remake map, more detail (maybe the performance will be a little bit worse)

Make custom colliders

Delete some useless flashlight features

Bigger map

If you would like to modify, add/remove, something write it in the comments.
