When I really about the game I realize it could be more educational if it used real plants, and if you had to take into account good planting locations...
Why not have the plants attract various insects...
Though, I'm just making excuses to avoid the suffering of getting the core gameplay working & finding out if it's fun or not.
The point is to make loot box loops work to get people exercising, not wasting money or doom-scrolling...
If games can be addictive can they be addictive for good?
