Overture

"Overture is a single-player Role Playing game that combines action-adventure and roguelike elements for intense and challenging gameplay. Explore vast randomly generated dungeons, engage in difficult boss fights, and collect an arsenal of weapons and loot. With 24 character classes and a chiptune soundtrack, Overture promises a delightful and immersive experience, but be warned: it will 'kick your butt and not apologize'."
