@morrilet Thanks for your comment! To clear up the confusion a bit, hopefully (spoilers!): There are four endings where 3 of the 4 NPC's vanish. When you talk to the remaining NPC, the NPC will say a few lines (press X multiple times) and the world will change. Once the NPC has finished explaining, the X key is disabled and the only thing you can still do is walk around in that "new world". The fifth ending (which I believe is what you got) is different: If the NPC's are unhappy with your answers (i.e. too many indifferent/indecisive answers), each one will tell you that once in an unfriendly way before permanently vanishing when you walk around the corner. After all 4 NPC's have vanished, the only thing you can still do is -- again -- walk around, but this time in the original world. So in all five endings, you remain stuck in some kind of loop, so to speak!
