The game looks quite good but there is a few issues, mostly with the hitboxes and colliders, you can partically go trough the door, the collider seems to be quite thin and at the first part of the game the battery and the note colliders seem to overlap eachother so the text kind of glitches. Also the batteries seem really useless, I did not have to reload my flaslight once and yet I got 2 whole batteries, just seems like a pointless feature.
The game is very short, I think the running scare is done quite well, but the atmosphere is a little lacking.
Most games atmospheres lack in the sound front, the reverb of the sounds does not match that of the place the game is in, its very easy to do this with unity (Reverb zones and such), which makes the game feel much more alive and makes the games much more immersive, also I think the footsteps should be alot louder.
There is also not that much tension before the scares, since there is no safety net or anything to imply a scare would happen, the scares seem random and just startle the player instead of scaring them.
The light cookie of the flashlight is also a little too jarring, looks kind of unrealistic, but still looks much better than if there was none!
Overall, pretty good short horror game.
Also this does not regard game design, but please optimize your games, the game has some significant lag spikes, for example when picking up the flashlight. And in no world should a game of this lenght be 250 mb-s, always compress your audio and textures and reaserch other ways to compress the build itself, especially for a jam game cause belive me, the quality of the game woulnt noticabely change and it would be much more accesible if the game was like 50-100 mbs.
