What a beautiful little game. I'm not sure if I'm misunderstanding the nutrient mechanic, but it seems like once you place and compost enough plants, there isn't a need to keep track of how many nutrients or whatever your pot has. I imagine you originally had some sort of trackers for the amount of nutrients in the soil that go up and down as you plant and compost?
Here's my little pot. I call it Wall Rosie. Nice game. Thanks for making it!
