Nice game. I liked the textures, they are moderately ps1 but still more detailed. Basically the atmosphere itself of such a very dusty place is pretty good. I would have liked more action, work the night shift or do some non-cleaning, and the game is short, but I got all the possible outcomes, so I went through the stages several times.
This is your third game I've played in which at the end you are running from an evil man in the room trying to find something like a key. Here it was easy, not like in Painter) And it seemed to me, or Brevsky really sometimes walked and sometimes accelerated a lot. If that was the case, that's very cool.
Good job!
