clever use of physics to collect all flags in each level. The shapes
that you draw are affected by gravity, friction and inertia. Use
these properties in your advantage. The
red ball (or red square in some levels), is the object that collects
the objects in such a way that they push the ball in the desired
direction. Use the mouse to draw an object. You cannot draw inside
other objects. Draw a circle by holding the left mouse button.
