Love this idea! Really liked the speaking sfx, somewhere between simlish and animal crossing - just wish there would have been more sound and music (shame about that breaking before the deadline).
Also really like the artstyle, though it was a bit unreadable whether or not soil was fertilized - and when the shriekers where done growing (I expect I was supposed to hear when they were grown up rather than seen).
I think this is something you could keep working on and release as a perfect "a bit too long of a bathroom break to skimp out on work" mobile game.
