It will be great if there was a button fast forward (to max lvl of buildings), because sometimes grind lower levels and after that have to click a lot on next button
I think that you should increase your hp, when you get hit in practise :D Especially when you are hit with combobreaker at 199 combo out of 200... your mental HP must raise twice HP it was before XDDD
It's definitely possible, with 2-3 hours effort, I have done it myself!
