Drain Mansion - Free Version

You awaken in an abandoned mansion with no memory of how you arrived, tasked with escaping while avoiding the supernatural threats within. The gameplay centers on environmental puzzle-solving and enemy evasion as you work your way through the mansion's corridors and chambers. You must push objects, jump through cracks, and use doors strategically to progress while managing encounters with demons and other obstacles. The game features a captivity escape mechanic accessible through inventory management. Multiple fetish themes are woven throughout, including reverse rape, femdom dynamics, energy drain mechanics, and explicit sexual content. The title emphasizes temptation and corruption as core narrative elements, suggesting moral choices or consequences tied to how you interact with the mansion's inhabitants. Save files can be transferred between the free public version and the Patreon-supported version, encouraging players to try before committing to support.
