Pretty fun! I can see this being expanded very easily too. I especially liked the cohesion between the sounds, art, ui, and the gameplay. The music and art is especially charming.
A lot of people below have already said a lot of what I thought, but one thing to definitely do is increase the hitbox sizes of the tiles. The visual for the tile is much *larger* than the hitbox. When I click, I have to click the small seed, not the larger square-ish tilled land. A bigger hitbox would just make it a little less frustrating to drag your guys there or plant/water your crops.
But otherwise I like this game! Good loop you got there
