Do you like to ski? how about water ski?
Easy to play yet it doesn't take the fun out of it.
You have to cross the finish line skiing down in the fastest time waving yourself between the blue marker which you have to take it from the right and the red marker which you have to take it from the left as you ski down the river.
You can play it by using the mouse where you left click all the way to make the play go quick and move your mouse to go right or left or you can use both mouth and keyboard where you click on the left button to make the speed acceleration and move the player right or left using the arrows on the keyboard.
You must go to the right of the blue marker and go left from the red marker.
