Before the present explosion of indie games, there was Cave Story. A sprawling, wonderful Metroid-style 2D adventure, Cave Story was the sole work of Daisuke Pixel Amaya, who created the game in his spare time while working for a Japanese IT company. Almost everyone who played Cave Story fell in love with it, and the game was a strong influence on the current boom of auteur-led indie titles. Pixel did everything himself — the graphics, the music, the programming, the story — and released Cave Story for free in 2004.
