The game is designed to trap players in endless smut scenes, with every decision leading to the same outcome: more smut scenes, world destruction and game over. After countless failed attempts and growing frustration, Arthur takes to the game’s community forum, venting his anger at the developers. To his shock, he receives a cryptic response from the developer challenging him to find a different ending. Moments later, Arthur is pulled into the game itself, awakening in the body of an unremarkable extra.

Can Arthur resist the game’s temptations, uncover hidden paths, and finally break free? Or will he become yet another player lost to its endless scenes? or he will do both? Follow Arthur’s journey for a fresh story filled with humor, plot twists, and concepts you won’t find elsewhere.
