Hey there, this message enticed me to try out your game; I just left a comment with my impressions on the entry’s page. :)
Ooooh, reading your comment again, I think I understand: the ‘good’ ending is the short one if you press X to leave early, and the other one is when you get the trophy! Then I did get the trophy and final dialogue (monologue?). ;) Still not sure about what the blue zones do!
