Position the command triggers on the field after thinking carefully the consequences aiming for the ball to collect all the stars before reaching the exit red flag. This is the goal in Simple Motions. You start with a few commands and as you advance in levels you get more as the obstacles are getting more too. Don't get discouraged easily! After a fail try you can always reset the field and correct the position of the command triggers to complete the level.
