Fuck Note

Fuck Note is an adult kinetic visual novel presented as a chat-based mobile app interface. After a humiliating night, the protagonist Hiro receives a mysterious message and meets KAss, a seductive supernatural entity who grants him reality-warping powers—but at a cost. Using his phone as a tool, Hiro can write names, set rules, and manipulate the people around him to build his own harem, though every use of KAss's powers drains his phone's battery, forcing him into increasingly intimate "recharge" scenarios. Gameplay revolves around chat interactions and player choices that affect encounters and character relationships. The game features a recharge system where using supernatural abilities depletes battery life, creating a resource management element tied to intimate scenes. Current content includes three free chapters introducing main characters like Yumi (a redhead Hiro is obsessed with) and Sora (a nerdy coworker), along with side characters and a gallery system. The game covers a range of adult fetishes including domination, voyeurism, group scenarios, and cheating themes.
