Multipliers do not work right, if I buy the food multiplier x2 then it multiplies your current value, not total. If you buy x2 then +2 it makes you lose out on total value.
It is not explained anywhere that you need to be a certain level to accept new quests or enter new areas. Should put a tip somewhere that explains why you can't do these things.
The final version will be up soon, with a cloud save system. No more file-swapping. :)
