Thanks! Yes, there is an actual win condition! Make sure you try combining plants, not just making it from one kind of plant.
I originally considered randomizing the plant taste/poisonousness and someone else remarked on that, too, so maybe I'll go back in and change that at some point. I dunno, though; the way it's made, learning which plants are good and which aren't is actually relevant, since you don't always get all the plants in a single game, and it isn't even guaranteed a map will be winnable.
More likely, if I go back in, I'll add a bunch more plants and limit the number of different types that can come up in a single game.
