Move your mouse around to drive the balloon. To change the colour of the balloon, click on it. You can also change the number of balloons by pressing the number buttons 1 to 3, which can also change colour by clicking them. Each balloon has different speeds: 1 being normal speed, 2 being the fastest and 3 being the slowest. Press "E" to play some music, and press "Q" to turn it off.
