How about playing football high in the sky? There is a platform, that is covered with grass, but too small to keep the ball for too long. Click on the screen to control the ball and keep in within the borders of the platform.
For how long can you keep the ball within the borders of the platform? There is not that much space to play football in the sky, but your goal is to keep the ball on the top of it as long as you can. Click on the screen to immediately change the direction of the ball and collect various flags on your way. These flags are used to purchase fun items, so don't collect some and have fun!
