You know this, it is your third lesson in the school, and next three are still ahead of you. It is boring as hell, and paying attention is almost impossible. Instead, you realized that you could have some fun by drawing an obstacle course into your exercise book. You came up with this: you must get a ball to the target area by using interactive objects like blocks or ropes. Move, delete, or create new ones, and see if you can get all three stars in each level. Have fun.
