the genius of sappheiros
Touhou Soujinengi The Genius of Sappheiros (東方蒼神縁起, lit. "Blue God Omen") is a fan-made Touhou Project game and a traditional turn-based RPG released at Comiket 78, heavily influenced by traditional console roleplaying games such as the SaGa Series. Despite being an RPG, it follows a traditional Touhou stage-based format, with each stage being its own dungeon. The game is made using the Unity game engine.
