I fully upgraded my town early in the game, and so now the only way for me to increase my power is by leveling up, and at level 39 that takes a while, and only gives me 100 power (which is practically nothing!)
Can you increase the power allotment upon levelling? Like 250 or 200? (That would actually be useful!)
Lastly, consider adding an “auto-battle” function, perhaps not an infinite one, but at least something…
