If you like a game that consistantly punishes you by otk. Play it. The enemies after world 10 basically just kills you in one hit. So it gets boring cause you just consistantly die. Sigh. Im gonna quit because of this. Its like throwing a lvl 50 to battle a lvl 60 that kills you in one hit. I cant pass it. I think its going to try force you to spend money. Edit based off reply. Ita hard to enjoy challenges if the game one-shots you without even a way to do better.
