東方紅魔郷 - the Embodiment of Scarlet Devil
東方紅魔郷 ～ the Embodiment of Scarlet Devil (romanized: Touhou Koumakyou, meaning Eastern Lands of the Scarlet Devil) is a challenging vertical-scrolling shooter, and is the sixth official game of the Touhou series. It is the first to be released specifically for the Windows OS.
The game takes place in the mystic oriental land of Gensokyo, as usual. The story revolves around the appearance of a thick red mist, that has covered the land and blocked out the sun. Playing as either Reimu Hakurei (a shrine maiden) or Marisa Kirisame (a playful magician), you must battle your way through 6 difficult stages toward the source of the red mist, and face the "Scarlet Devil" behind it all.
PyTouhou is an attempt to rewrite the engine behind The Embodiment of Scarlet Devil (EoSD), a popular danmaku (bullet hell) game published for Windows by Team Shanghai Alice in 2002. Although the main reason behind this project is sheer curiosity, other motivations are portability and extendability. Additionally, this project aims for a perfect compatibility with the official game, and thus become some sort of reference implementation.
