I liked this a lot, it shows promise. The footsteps in the tunnel got me good. I did notice one bug - after picking up the glowsticks on the first train car, I went the opposite direction and was hit by the train. When I reloaded, the light from the glowsticks was still visible on the seats where I had picked them up.
Other than that, not much more to say. I look forward to seeing where this goes!
