Ok I just played it. Most of the time I end up outside with police ready to arrest me x_x lol. I faced some blocked exits too and there was one route which took me right back to Poly U too.
Interesting PolyU escape simulator XD. Just a question though, does the direction I'm moving towards, after the timer bar is empty, get affected by where my mouse is pointing to?
Hoping there's an exit without police around to arrest me x_x hahaha
EDIT: Actually I heard the sewers are infested with rats or snakes.
there is indeed a successful escape state, but since this was made for a "screensaver jam" there's no player interaction to determine direction or anything. it's just a random selection each time. sorry you had bad luck >_<
