This game should get five stars but I'm giving it one for reason and I'm a 75 in there but still it's getting one reason why the game freezes too much in battles also you don't get very much payouts not enough to upgrade anything and also the further you level up you see less and less of technology of older units and you can't go back to upgrade all of them they need to make it so that when you do events you earn unit upgrades for all units that you have unlocked not just the ones at your lvl
