Magical Dungeon Search! Oxygen-chan

A roguelike dungeon-crawler featuring Oxygen, an element girl (a humanoid being with special powers) searching for her missing friend Hydrogen. Descend through a three-level dungeon, collecting items and battling over 30 different enemies. Combat involves strategic use of status effects and exploiting enemy weaknesses—though enemies will attempt to incapacitate Oxygen through various means. The game offers flexible difficulty options: some modes allow you to retry from checkpoints without losing progression, ensuring no content is locked behind perfect runs. Features include a gallery system to view unlocked content and character information, score attack mode for high-score competition, and extensive erotic defeat scenarios with 15+ CGs plus additional event artwork.
