Precision is everything, just don't rush yourself...
Complete the obstacle course ahead while passing through targets. Passing through the center of targets gives the most points.
Red/Yellow/Green targets give 5/15/40 points respectively based on your position as you go through the target.
Blue/Purple/Blue targets give 10/30/80 points respectively (ie. double points)
Any time under 60s will earn bonus points: 1s = 1 point
