congratulations on completing a jam! I would highly recommend increasing the time taken for crops to grow, it is so quick that you never get a chance to utilize the entire field, some instructions would be helpful too

Cute graphics. Definitely theme appropriate. Nice and easy controls.
Some text, either in-game or on the itch page could go a long way to clearing up what you're supposed to do in the game. It became clear but I was a little unsure why you wouldn't take the most expensive crop each time, since you always seem to double your input. A timer or other obstacle could go a long way.

I enjoyed becoming a millionaire running back and forth planing and harvesting beats. Very cute.

I suggest turning off "filtering" for your pixel art sprites so you don't get any blurred lines.
