Cybercoaster is a homebrew arcade-style game for the NES by demoscene authors fizzer and noby. From a first-person point of view, your objective is to fly through a colorful tunnel and optionally collect pink balls. In the later levels, there are walls that you can crash into if you don't avoid them.
In this run, CoolHandMike sets the speed to maximum and deftly plays through all six levels as fast as possible.
