I actually enjoyed this more than other farming games like harvest moon and stardew valley! Like others mentioned, the atmosphere in this game is really good and I'm glad you implemented up arrow to repeat the previous command.
Is the nimbusmelon final seed you unlock? I couldn't figure out how the outofcontrol command worked either :p
One small thing that would have been helpful when first playing the game is some indicator of when a plant is ready to be harvested since it's not clear just from the sprites. I think perhaps either some sort of outline around them. Alternatively a text description would be more flavorful and fit in with the game's mood.
The setting also reminded me of the movie Weathering With You. It would be cool if there some more bits of lore about the rain sprites!
