It's not a bad game but my only concern is continually opening the map over and over because all of the halls are literally the same not much difference to tell what floor im on or anything. (since your using unity, you can simply add a recolor function to your texture for each corridor or a color tab line like most corridors do in modern facilities, it will help differentiate between say hall A or Hall D)
Love your art style so far, wouldn't mind being able to see more things relating to Game over raping though (but that may just be me). Story is certainly coming along well.
