!!!SPOILERS!!! for both
So does Happy World take place after Happy Zone or maybe in an alternate universe in which you never helped the people from Happy Zone?Since Purple says he/she is suicidal in Happy Zone and Purple is dead in Happy World, does Purple never find his frogs corpse and proceeds to commit suicide? Same for the Skinless Woman: You find her skin in Happy Zone but she is still "skinless" in Happy World. And finally the blue guy is still blue in Happy World and there is no pink guy so is this the same blue guy?
Also is there any point to doodle zone?
