Game was fun till you hit a wall around stage 6 or so. The game doesn't have enough in game currency rewards for you to be able to draw to power up your team. You get 10-50 diamonds on massive achievements and need 1900 something to summon. I've been able to complete 1 10x summon from diamonds and that's all. It give you 2 free summons and not enough power to do anything or progress without grossly p2w. Stage clear rewards is gold not even diamonds.
