There's a little bit of lag when you switch between upgrades and producers tabs. At first it's not something you should have to worry about, but when you unlock food production it becomes quite annoying and i suppose it can only become worse if i keep unlocking markets.
You have to put in this game more....more...MORE in general. The game is empty, i don't usually vote 1/5 but you deserve it ;). "Zombie hunter", no zombie, no hunting whatsoever, you should have called it "Missions work arena: the nothingness"
I got caught in the update and now i have 170B coins and 60k ooze... and the 2nd hero seems broken. For example: if i match 3+3+4 of the same color i don't earn the ooze bonus, but if i match 7+5 i earn it. The problem is that in idle mode is almost impossible to match 7 more oozes
