Use WASD or the arrow keys to move the ball around and press space to jump. Don't fall off the level, or touch a tile that will destroy your ball. If you do, you will have to start over!

There are two ways to play: In score mode, try and collect all of the coins without falling off the path or landing on a red tile. In timed mode, you have to collect all of the coins and complete the level as quickly as possible. Try playing Score mode first, and come back to timed when you're ready for the challenge. You can press Escape to go back to the main menu if you want to switch modes.
