Very cool with satisfying puzzles. I think you nailed teaching the mechanics, really intuitive. Some things I think could improve the experience would be to have some kind of overlay when placing the objects to show what they would affect, and/or while they remain placed, the area they affect. Maybe like darken all the squares around them that they are, or could be affecting. Another thing that would be nice would be being able to move an already placed plant to another spot without having to press undo.
