Hmm, I think it could be nice, but I found myself frustrated and confused with a lot of aspects.
In theory, the concept of handling farming through a series of actions that have randomized areas is novel, and could create some interesting strategic play and improvisations where you have to make the most out of each action. But for the most part I should found myself utterly confused and irritated since it was completely random and without any ability to plan beyond dumb luck: perhaps if you were given a preview of the next area similar to Tetris, or if you were given a set of action cards and a set of area cards each round that you can combine, then I'd feel more in control and less annoyed.
There were also other slight annoyances, such as the full area of effect not being visible if you have part of it going off-screen (would prefer if the full area is always visible, but highlight the part outside in a different color), the rules being unclear for how to plant and harvest (is overwatering bad, can you still grow an in-progress crop in ground that has faded from tilled, where will the seed be planted if I have a triple area but only 1 seed on me, etc) and due to the lack of a separate hand action or perhaps the cursor changing to a hand icon when over a fully-grown crop, I was unsure how to harvest things as I was fearful of destroying them with a click from one of the tools (perhaps harvesting should be automatic at round end).
It's a game jam game, so it's perfectly fine to experiment like this, and it's understandable the game is not as juicy and polished as I'd like, but in the end, this felt pretty bleh for me. Not a bad idea though.
