In addition to what everyone else wrote below, this is super polished for only one month! Especially the pixel art for the butterflies, they look incredible.
I think the main things for me are:
a basic tutorial popup showing what wilting flowers look like, why you should get rid of them and how to do so (wasn't totally obvious to me to begin with, I forgot a lot of the email text soon after closing it).
So cool how you have basically 4 games in one though: gardening, bug catching, quizes and filling out the dex!
