Again

Again - an unusual platformer in which you have to play for miserable Green. He doesn't know anything about himself except for his name and goal- to find a way out. You are tasked to find a way out for Green from the world of islands, but there is a problem that doesn't let the hero finally get out - incomprehensible branching of the transitions between the islands.
You have to overcome the islands one after another collecting coins on your way, which are an indicator of the passage of the game. At each level there are several doors, but only one of them leads to the next level, and the rest return the hero to the beginning and completely erase his memory. Or not completely?No one can know until the end...
