great game, just needs abit more time in the oven. here's what I would suggest adding into the game.

-Add more ambient sfx
-Add more interactions with the monster
-put a ever so slight shadow in front of the player with the sillhoute of the monster
-whenever the player moves, there will be a random chance to trigger a footstep sound behind him
-sliders to change certain settings (ChromaAB, FOV, Motion blur, resolution, etc)
-fix the depth of field

Hope this all helps!
