You are Astyanax, a sixteen year old boy that has the same dream night after night: A princess, calling for help. One afternoon, you are summoned to the world of Remnia by Cutie, a pixie, to save the realm's princess. You are the chosen one mentioned by their prophecies!

Astyanax is a side-scrolling platform action game set in a fantasy world. You must save the realm from Blackhorn's evil horde. Along the way you'll find powerups that will make you stronger, and upgrade your weapon; and you can also unleash magical attacks that hit all enemies on the screen.
