the game is good, but it is too focused on the defense of the last level. it would be better if each level was defended separately, so that the attackers have to defeat each level separately

Can no longer play online, it's been months now. I've purchased the starter package only to be denied the privileges. When in online mode, I am in a state of checking internet connection forever. I've tried reinstalling and switching on/offline. As online and offline progression are seperate, there isn't an incentive to continue this app.

It's a great game with great concept i thought it would just be so easy at first but i realized i was just in lvl 0 category and I'm already having a hard time, this where you learn how to really strategize and use the game mechanics meant so that you can improve and beat the game, overall it's been super fun simple yet entertaining it's already good as it is but if the Devs finds something to tweak something in it then i fully support them. Great and nice GAME
