I liked how there are lots of pictures to look at. I got 2 endings. They were kind of creepy.
Now, about the issues. The settings wouldn't open. The controls aren't stated anywhere in the game. On credits page, some symbols don't really show up, as in the screenshot:
On ending text, there's also that stuff.
So when I was going for 3rd ending, I just walked down the tunnel. I was walking for a good minute, and nothing was there. Just pure dark. The station was quite far away so its light was a few pixels in size. Then supposedly train was arriving and everything's bugged out, there was not light, everything was dark, some sounds were playing but not too much. And no ending screen. That's it.
