In Roller Boaster, you control a ball and help it win each level. It's easy to control the ball. Use the left and right arrow keys to move left and right and use the up button to jump. If you want the ball to jump higher, hold up for a longer period of time and he will bounce even higher. You'll hit different power ups and boosts throughout the game that will make it easier for you to win. You want to collect coins and medals. There are rocks, falls, and other dangers in this game. Keep an eye on the timer at the top of the screen.
