It's really hard to give proper feedback, since I am scared really easily.
But one thing I did notice, it that I many times found myself unable to escape, mostly because of a dead end. I noticed I can hit with my torch, but I couldn't figure out what it actually does.
Looking around isn't bad but somehow is felt strange. But as for all first person games: please add a sensitivity slider.
I didn't get far in the game, but the atmosphere was nice, you managed to get me scared. Although it relies heavily on jumpscares at the time. But those jumpscares help make to atmoshpere, so...
If I can point out one thing about the graphics is that the textures repeat really often. I assume this is a subject of change in the future, but thought I would say it nonetheless.
