I think this would be a cute little experience once it's got mor functionality and gets polished! I think this would be a good format for telling a story through environment, unlocking new areas as you clean up the already unlocked ones.
I think one of the big things missing is indications of what I can click on / interact with. Some highlights when mousing over, or desaturating the background so those interactable elements pop, would really help.
It would also be nice to see which tool (garden sheers vs seeds) was selected.
