I would like a Raise All Ranks- 1 Level Button. Multiple times I have many soldiers that are displaying rank raising, but it's such a chore to click on the player, Click again to get to the rank screen, and then click the next rank. 1 Button, to raise everyones level to the next - as for the gold it would keep going until it was exhausted.
The weapons aren't strong enough / the upgrades are weak
If the towers fired faster, it would be better, that would compensate them being weak.
I've tried multiple towers, and i can only make it to level 4 (barely).
Game play is frustrating
