I am very late to the party, but I'd just love to say how stupidly fun and simple this game is. I have my garden in my home office and I play once a day for weeks now. That's a nice way to take a new look at my dice collection.
I even wonder if I wouldn't add this to my solo or one-to-one regular TTRPG campaigns. Harvested dice (or the ones that have bloomed) could be used as one-time bonuses for druids or other nature based classes.
