nice game, but it's too easy, i think my army are to overpowered, maybe you can make this game a bit harder, so it wouldn't be too easy to become overpowered. i became overpowered in just 3-5 hours. and please add (a) button(s) to max the upgrade, my hands are burning when i level up my army 50+ times.
