He is keeping to himself because of his girlfriend's death. He goes to the green box because he does not like open spaces and doesn't feel safe. The falls remind him that death is a possibility. The pink forcefields say that if he tries again, it will not work the second time. The green forcefields say he must try multiple times to achieve something. He feels that he can work better by himself, though he must learn to work with himself. He feels vulnerable out in the open (it mentions this in the irritatingly spacious level.) The last level is a reminder that he must jump into empty space and hope for the best. This game makes perfect sense if you think about it.
My heart was racing when i came down from the lighthouse and went back up again. It was also racing when i grabbed the pickaxe. (between this and slender man i don't think i'll sleep tonight. 5/5 anyways)
he must have read "running from t-rexes, lava water etc. by using parkour, gliding and whatever else you can pick up, a practical guide." Not very practical now, is it?
