the objective of the game is very simple – to guide the red ball from a predetermined start point reach the yellow star.
as explained to me by my six-year old boy, the yellow ball and almost all objects on the screen are affected by gravity. one cannot control the ball directly, but rather must draw something – a box, a wheel or a rope, or just a line- in order to INFLUENCE the ball to move towards the star. in some levels, there are rockets to help the ball reach the star. one needs to draw something strategic to lauch the rocket, push the ball and reach the yellow star.
as i watch my boys play, ive realized that the challenge of the game is to come up with creative solutions and not just plain doodling and scribbling of lines and shapes. yes, crayon physics is not as easy as it seems. but my boys aged nine, eight and six enjoy it so much and have completed the 60 levels.
