Supernova is a runner-style racing game that features a spaceship theme. The player directs a spaceship along striped geometric racetracks through tunnels and obstacles across multiple levels. Their only goals are to reach the end of each level and unlock new spaceships at levels 3, 7, 12, 20, 30 and 40.
The tunnels have wavy shapes with blended and contrasting colors that make it difficult for the player to direct the spaceship easily. Racetrack obstacles include archways, columns, rings and walls. The player has no control over the speed of the ship. It travels automatically at such high and modulating speeds that the player can have difficulty seeing an upcoming threat. They must direct the ship around obstacles quickly to prevent a crash.
Supernova's color schemes and object shapes make it seem like the walls undulate, which can cause confusion. Additionally, color brightness and shades change rapidly. The player must keep their eyes on both the ship and the horizon to make certain that they don't crash.
It's important to note that this game features combinations of flashes of light and object size changes that might cause health problems for some players. If a player has visual difficulties or experiences seizures from bright or flashing lights, they should speak with their personal physician about the game before playing it.
