A good mix of frustrating and relaxing levels, the pencils drove me crazy and then afterwards I could relax by straighening up some pictures.
It was a bit difficult to know when I had clicked on some of the objects and what direction they would change when released, could improve the game by giving some sort of visual indication of the direction something would go when picked up.
Other than that it's difficult to fault, matches the theme pretty well and is the perfect balance between frustrating and fun.
