Well done! I like how the mechanic works with the narrative. Even the window size supports the corridor/monotony theme. I would only say that the music is perhaps a little too repetitive and btw there's also a couple of typos (it should be 'did deserve', 'too scared', 'your hair').

Perhaps it would be better to close the window at the end? You could also make sort of a 'ka-ching' sound when the dude passes the register — otherwise it is quite easy to miss what happens with the cash balance. Or better yet, make the player interact with the booth to purchase the ticket, without which it would be impossible to pass some sort of a turniquet?
