Code Magic: a Programmer's Fantasy Maze

Vincent, a college student from Earth, is transported to another world filled with strange powers and bizarre monsters. Ideally, this would be the beginning of his journey to becoming a legendary hero, building an eternal empire, and amassing a private harem. But no one said this new world would be easy... After escaping an unexpected assassination, he is forced to become a Dungeon Master. What does an average student programmer do when he discovers he can code dungeons? Use his skills and savvy—and an army of golems—to defeat those barbarians above? "Wait, this world isn't medieval at all?!" With all his questions in mind, Vincent is ready to uncover all these secrets! And... Conquer the world, maybe?
