No balance
I really liked the game but like most freemiums it has a high pay for good heroes. The tutorial allows you to partner with crow and blaze presumably the best characters you can buy but it will set you back $400 big ones to acquire these guys. Then to make matters worse there is no balance. If your castle is lvl 50 and all your heroes are lvl 35-40 then you will get paired up with lvl 50 and have no way of beating them. Basically adapt or die is. The motto end game.
