Use the mouse to aim and click or press space to boost in that direction, hold the button to fly. You can also use a touch screen or a track pad, but i recommend you use a full size mouse/trackball. Boost into a trail of lights and they will pull you along. Boost into cracked blocks to break them. Colored bumpers restore health. Colored lights ... well you'll see.
Please tell me what you think of the prototype. Do you like the mouse controls or should it control more like a normal platformer? Music from Sonic Mania. Update: Changed flying physics to be more responsive.
