As cool as the minimalistic "figure it out yourself" vibes are, I think the game is lacking a way to teach players. I messed around in the first level for a couple minutes before reading the spoiler details and I was still confused. After messing around for another 5 minutes or so, I gave up once I got 4 green tiles to turn yellow (with harvesters next to them) and I still didn't pass the level.
My thought as to how you could teach the player while retaining the minimalistic vibe is to cut back on the mechanics presented to the player from the start. Give them a couple levels of just green, blue, and grey (if soil or pests are required to grow crops, I did not realize) on a small board. Then from there, very slowly add in complexity or a new mechanic. I may simply not understand an obvious mechanic; however, even with the tips, I still couldn't figure them out.
The music and art-style is perfect though! I will likely come back to this game and give it another shot. Maybe my brain is rotting from coding all day every day, and fresh eyes is all I need.
