First you have 10 seconds to prepare. You are the purple line. You can slide the variable "player speed" to change the movement of the player. For Saturn it's the same but you have to slide the variable "Saturn speed". You can move by pressing right arrow or d and by pressing the left arrow or a. You have to stop Saturn by letting him not touch the water, but touch you. You have to do this for 50 seconds long. If you proceed and letting him not touch the water for 50 seconds, you win. If you don't you lose.
