Alright, I've found a deeply circumstantial problem. In the event of battle being perfectly equal, to where it's impossible for either side to take an advantage, the battle will just sit there forever. Perhaps a hidden, like, 3 minute time out? Or a forfeit button?
Fantastic upgrade, but there's one tiny thing I can't stand. Click power and auto click power being in the same upgrade. I like the challenge of upgrading just click power, never relying on auto click power. Course, wouldn't dream of asking you make a new tree, but maybe a button next to the work button or in the options to disable auto clicking?
