Well, at least my finger thinks thinks the auto upgrades should come sooner. And I think I was at manager? I didn't pay much attention to the exact title.
Also, I'm not sure if I misread them, but I think the price of the first couple upgrades are higher than they actually are. I ended up saving more than I needed at first because of that. (Not to mention hitting a couple half money penalties along the way.)
The chip storage mechanic should probably be better explained. I assumed the heater prevented any loss. (Also, why heater? I've never heard of hot potato chips. Unless we're not in the US, which everything being listed in dollars makes me assume.)
As for the wheel, I'm a little mixed on that. The bonuses are nice of course, the penalties can be a bit steep, but the worst one is the canceled delivery since that basically trashes the entire next day if you're able to peel every single potato you had.
Shift length? Maybe a solid minute to make things a bit more comfortable or make a third batch possible if you got really fast fingers.
