Fairly good atmosphere kept the tension high. Fairly interesting story though I don't think I fully understood the ending. Did miss things for a while though that was due to the fact I was walking near the tracks, ended up missing things at the top of the area especially the ticket booth. I agree with other commenters that shrinking the play space would help with leading the player took me a fairly long time to realize that the area was looping.
Solid entry overall, Great Job!
