The Curse of Issyos is a retro styled action platformer with nothing but the usual in an old 8 bit game: a good bunch of enemies and bosses, linear and open scroll levels, secrets to discover and a background story inspired by Greek mythology. It doesn't try to mimic a retro system in particular, but it's coherent with its own limitations in the use of colors, sprites and chip sounds. The soundtrack has been composed by Gryzor87 using Pixel Amaya's PX Tone.
