I think this is a really interesting idea! I hadn't heard of the Miyawaki method before, so I think your blurb plus the gameplay gave me a pretty good idea of how it works! That said, I would love for that blurb or something similar to be in-game, rather than in the description. As for the aesthetics, I think the game looks great! I would work on the sound design though. I imagine you're using placeholder sounds right now, but consider what kind of sounds evoke nature, and see if that helps with the game's ambience. Speaking of, it would be interesting to see if you could have nature sounds that slowly grow in volume as you plant; you're essentially creating a forest, after all. Having that natural ambience, and diegetic sounds would really improve the gamefeel. Overall, I'm very excited to see what else comes out from this project, great work!
