Add some new food options. These new options should take MUCH longer to grow. Their cost should be somewhat higher but not substantially higher. For example, a new food called "Monster Sprouts." It costs 300k gold to produce. It takes 4 hours to grow and produces 12,000 food. This is essentially like Rainbow Snow Peas times 4 on everything.
I think it would also be good to have a type of food that takes 8 hours to grow. The benefit for this type of food might help numerous different kinds of players:
- All players could change their farms to produce more food while they sleep.
- Younger players who are not allowed to bring or use their tablets or phones in school.
- Any player that just wants to play the game more casually.
