The animations were very charming. There's something about the push and pull art I liked a lot :P.
What might be cool in the future (if you keep adding to this) is add puzzles that need you to figure out how to use multiple items when you can only carry one. I found myself a few times positioning items so I'd have access to multiple at once (like dropping items on top of each other to push one of the edge). Could lead to a couple fun puzzles :)
