I really liked the style and art and it felt super relaxing to play! I feel this is a great base to a game. For the theme of the Jam, the time I felt out of control was when the cloud appeared capturing the theme. Maybe doing that earlier and adding things like Baseballs/Soccar balls that get kicked into the yard as you mow or as aweful as it sound, birds and rabbits darting in and out?
Overall, this could maybe be a stand alone game maybe made into a puzzler game outside of the jam!
Cheers!
