Maybe I miss something but it is extremely hard and tedious to maintain energy.
Why it is hard?
After losing to a girl you lose all energy and regain a tiny bit by sleeping. Eating is very expensive (50 bucks). Many jobs you can do costs you a reasonable ammont of energy. So you often lose what you gain.
On top of that if you can not pay the rent you lose 50%! of your current energy while sleeping which often leads to zero.
Why is it tedious?
Because after losing your energy is zero or nearly zero. So every lose means replenishment and to do so you need money. So you are forced to grind.
I do not like that the neighbor steal so much energy is much that removes, anyway if you go to the city from the first day and work in bakery you obtain about 70 dollars, working 2 days and you have more than 100 dollars and the rest of days of the week you can do What you want because the neighbor charges you once a week and only 100 dollars, as far as food is right is very expensive, but I do not like, I'm just going to do something and if I kill or I have no energy then rest in bed
