Nice game, I enjoyed this a lot! :)
The mechanics of having three types of flower with three different consequences on the world is really interesting, because each of them helps you grow further and plant new flowers, in a sort of positive feedback. I really felt the "engine growth" sensation, and that a big plus for me! I'd loved to have a way to choose what flower I was sowing, but I also think that having them randomly generated is quite... zen :D
Great submission, congrats!
