I loved this game! The challenge level was managable and increased just the right amount for me. What maybe could be added is an undo step button.
The way I played was that I planned out the whole level before even moving the vegetables.
The farmers sight was a bit unclear of how it worked at first. Maybe add a visual for that, including length. But as I noticed it seemed to be "endless".
The last level was quite ingenious, but I managed to solve it in the end. But one of the carrots was not needed. Was that intentional? :)
