i played it and was confused like everyone else. searching the web and seeing what others are saying, it's not so much a game as it is a short story told through in game format.
the comments by 'a rob amongst many' and nocturnal kinda explain it:
there's also other things nifty things like the green cpu on the start screen showing water = death. also there's probably some meaning to the fact that bad guys pretty much don't do anything unless you touch them (ex: the sprinklers cant hurt you, maybe the robot perceives them as bad guys even though they are harmless?).
