As soon as I saw the screenshots I knew I was going to enjoy this entry and you didn't disappoint ^^
Albeit short, I loved the story, aesthetics and setting. Had enough intrigue to hook me in. I compared it a lot with a game called Detention which had a very similar premise.
With more polish, you will have a nice foundation to build an amazing Horror experience.
What I would recommend looking into;
1) Movement Speed; I felt the character was running and turning too fast
2) Coverage of Out of camera areas; There are some instances in which the player can move outside of the fixed camera angle perspective; I'd suggest having does cameras be able to rotate to those areas so that the character is always on screen as much as possible.
3) More ways to out maneuverer the enemies; I Imagine the game would mainly focus on a hide and seek aspect; So more ways to lure enemies away or to a certain position would aid in creating a more dynamic experience.
Amazing work! Keep it up!
