How about money rate upgrades because seriously, money is slow :( also, how about upgrades for the bank that increase amount of interest given and reduce the timer for it? Obviously they'd cost loads and loads, but yeah. Need MOAR UPGRADEZ, UPGRADEZ FOR EVERYTHINGZ, I NEEDZ TO UPGRADEZ
I think there needs to be a lot more upgrades and better more useful features, such as better minigames that give rewards without having to pay for them over and over again.
