Draw with your finger, then press Play. Buddy slides down whatever you draw. Press Stop to change things and try again.
Track lines are what Buddy rides on. Boost lines (orange) speed him up the way you drew them. Scenery lines (green) are just for show.
Buddy lands on the top of a line. Draw lines left to right, and a loop in one go, anticlockwise.
Tools: pencil to draw freehand, ruler for straight lines, rubber to rub out, hand to move about. Pinch with two fingers to zoom.
Challenges: reach the flag for a star, catch every bone for another, and use no more ink than par for the third. You can't draw on flowerbeds, and thorns knock Buddy off.
