Happy Happy Office

Happy Happy Office is a 2D stealth-action adult game where you navigate an office using a mysterious love app created by a succubus to pursue romantic encounters with coworkers. The core gameplay combines stealth mechanics—avoiding detection by other employees, managing noise levels, and finding hidden routes—with light puzzle-solving to unlock doors and reach secret meeting spots. You must time your movements carefully and study your surroundings to progress through 27 stages without getting caught. The game features 18 distinct heroines, each offering different romantic and sexual scenarios as you build relationships through the app's supernatural influence.
