Lasso Challenge

The objective of the game is to get the right colored balls to touch the white ball in the center.
This is done by drawing a lasso round the balls, separating them from the other balls which mustn't touch the white ball.
The number and the color of the balls which must touch the white ball varies for each level. It gets more difficult for each level.
You get a score for each right ball and bonus-points for stars. If your total score is high enough you get into the highscore list.
