Getting Started
When you start up the game, you already have almost all the levels unlocked. Although you may be eager to play the harder one's, stereo madness is where you should start. On the main menu, you can either play the main levels, customize your icons, or create and play levels online. Try customizing your character with your limited options and then heading into the first level.
Customization
There are over 100 different icons to choose fom once you have all lf them unlocked. But if you are just starting out you will only have a few.

As of 2.0, the vehicles include; Cube, Ship, Ball, UFO, Wave, and robot. The 7th catagory with the star is your trail. It will appear when in some vehicles or when using certain elements.
Online Levels
