Viriax (2011)

Viriax is an experimental game with procedurally generated levels. The player controls a virus that advances in order to infect the main organs of a human body. Every movement has an energy cost, so he must absorb red blood cells to keep going, taking items along the way that can cause all kinds of mutations and unexpected effects. It features raw visuals and a sick soundtrack composed by Gryzor87 with PX Tone, the chip music tool created by Daisuke Pixel Amaya.
