Thanks for sharing!
That was enjoyable. I think I would have gotten frustrated in another level or two but it stopped right as I was reaching the end of what's easy to me.
The only improvements I can think of are QoL. A badge over a seed to say how many you have placed and an outline or something indicating the currently selected seed. Especially for us colorblind, it would make it much easier to glance at the seeds and see what we still need.
