Mugen no Meikyū series
Group DescriptionMugen no Meikyū (夢幻の迷宮) is a series of adult games by Software House Parsley. The games share a common setting, mysterious desert labyrinths known as "Phantom Phenomenon" and the underground land of Ge-Pang. There are also recurrent protagonists and other characters. Later installments introduced sci-fi and post-apocalyptic elements to the initial fantasy setting.
With a few exceptions, most games in the series belong to the role-playing genre, more specifically dungeon crawlers influenced by roguelikes, with randomized locations and items, and an emphasis on surviving long dungeon-exploring sessions without being able to save the progress. Combat system shifted from real-time to action in later installments.
