Thank you for the feedback! Yes, the clickable area on some of the icon placement sprites was definitely a bit too small; I'll be sure to use larger hitboxes if I do future point-and-click style games.
The issue i experimented didnt involve the clickeable area, and had more to do with something happening, after you place something, say a flower, that prevented future clicks for a while.
Oh, I see. Unfortunately I can't resubmit, but I'll take a look to see why the toolbar isn't immediately available after placing an item. Thank you for the feedback!
