The game is a neverending grind. The reward system is pathetic. Gameplay is repetitive. Hero upgrading is overly complicated. You're severely limited with gameplay, as once you burn your game tokens you have to wait hours to do anything else. Most of the game stays locked until you've invested a regrettable amount of time into it. Not only all that, but the characters and their ai are dumb. The game is hard on new players. Making them want to quit after the first few games.
