For some reason this game reminded me of Tetris where I would wait for the perfect 4-block line to complete a Tetris, similarly here I would keep placeholders where I was hoping for the perfect 4 edge color combination to score a huge chunk of points at the same time.
Really fun concept, I won't go further into the visual issues already provided by the other comments. I love the vibe that I got from playing this. No time rush, just plain old fields with beautiful guitar chords to celebrate what I'm planting. I loved the details in the sounds (the birds, flies, etc), some of the visual details like the clouds etc that just add on to the game.
I think if you fix the visual, you could take this concept quite a bit further. Ideally you remove the RNG completely so it becomes purely strategy.
Loved to play, great job!
