Hello there, just tried your game and i can say that you make some very good mechanics, the player movement is super great but i didnt get if there's stamina since the running is a bit weird since when pressing SHIFT gives you only some inertia and that's it. The flashlight beam and the cookie are working very great and i like it. I guess for now it's only a demo or something very raw but you made a good start, i got the slenderman vibes plus great player control which is very pleasant.
I really like the tapes and the voice acting too.
My overall suggestion is to make the game more various and dynamic, altough is super great for a start!
