This game makes perfect sense to me. You used to work as a bodyguard for the guy in the green, but he fired you so now you want to kill him. The game is set in the future, after a nuclear war so you live in a bunker with no exits. Your boss had dementia so he sometimes forgets that he fired you. And to preserve energy they dimmed the lights in the bunker, but unfortunately the guards can't see very well in the dark. You can't use a gun because they are illegal unless you are currently a bodyguard. The reason the exit pops up at the end is because you're friends from another bunker tunneled in to help you escape... Its all so obvious.
