I really like this! The only thing I'd say is that there seems to be no point to the market system. Like, I have insensitive to sell my new flower breeds for the money, that makes sense. But then I can only spend that money on new flower breeds, but, I have no desire to do that, because the fun of the game for me, is breeding those new flowers.
I feel like more money should let you buy a bigger garden, or give you more organizational tools. Especially because with these types of games, I'm always looking to organize and expedite what ever the main process is. So like, money should let me buy flower beds or something like that.
I don't know if you were looking to make this a 'flower breeding Factorio', because that's essentially what I'm suggesting, but I think that going in that direction would be fun.
Hopefully any of that was helpful.
