Great job in building the atmosphere with the sound design and over all look of the place. Small random occurrences were nice too, although the skeleton lockers got me laughing way too hard, but that's a good thing I think. Regardless, this was a tense experience and the ending sequence was nice way to end too even if for me it became more of an action sequence. But mad respects for re-using your level design like that! I love how the levels were build, you could see that some design actually went to making them work. I must also say it again, the sound design was great and really got me on the edge of my seat.
The game is basically finished and gives a short and fun horror experience, so good work! I mean you can always develop it further but I think there is nothing more you need to add, except maybe some usage for crouch lol. Respect for doing sound-options tho!
