Pretty good atmosphere for the game and a pretty good level design.
Things to improve on:
sound a bit funky (mostly the talking guy to much SFX on him)
The "RUN" text is a bit meaning less when you cant run + its a bit hard to read (use text mesh pro)
and a nice "bug" if you hold W and D (or A) you will walk fast ;D
The biggest miss to show more the monster and maybe a chase scene when you are slowed with the hammer.
Things done good:
good horror setting
the walking (especially the hammer lowering the speed)
level design is great and you can understand where to go
Great job!!
