Too short
While the gameplay was good, the whole game seemed like a bit of a tutorial for more levels rather than a game in and of itself. I would love to see this game done with a larger level pack, since I was able to finish the whole thing in a matter of a few minutes.
I did run into a bug where releasing the mouse outside of the game causes items to stick and become un-draggable. To see this for yourself, drag an item off the stage (ie. out of the flash movie's bounds) now release the mouse, then move your mouse back in and click the item. Now try to move it.
