Wish the escape button did something, like open settings while playing, or go back, as it does in almost every other game. Also, I was under the impression it's an idle game, but it is only to a certain extent. You can get through most levels idle after making all upgrades, but you have to fight the bosses. Also, I have all upgrades now, tons of money to spend, but nothing to spend it on. So this game could definitely do with more upgrades to spend your money on.
