The enemy AI and the RNG in this game is insanely imbalanced after level 15. Everything else about the game also gets super poorly designed after that point too. Goes from being a really fun experience to an insanely frustrating one at the drop of a hat. Latest update included no balance changes either. This game tries to trick you into thinking it's a well designed mobile game, and right as you get comfy it pulls the rug out from under you. 100% would not recommend.
