Good concept and well designed levels. It felt very much like a platform puzzle game playing through it. I liked having the camera follow the ball and the lack of pause added tension, but it did add difficulty when trying to change the placement of jumps. Perhaps making Left click add a trampoline and Right Click remove them (to avoid accidentally adding when trying to remove and vica versa) could solve this problem. The music was very nice and soothing and helped keep it light. The bonus level was a nice touch.
