Game never gets any harder than it starts. 151 levels and then they all repeat starting at 152. Feels designed to be a shell of a game so they can deliver ads, too bad I have an ad blocker I guess. They use fear tactics to try to scare you into watching their ads when you get a new character by saying "If you miss it, it may be gone forever!" Absolutely blatantly untrue as they offered me the same character several times through the course of the game. Avoid this piece of garbage.
