High School Master (v0.372) is an adult-oriented simulation game by Pervy Bunny Games
Pervy Bunny Games has accidentally built a masterclass in emergent narrative. Because the systems are so robust, players have created "challenge runs" that the developers never intended: the Pacifist Master (rise to the top without a single lewd interaction), the Chaotic Neutral (randomize every choice), or the Speedrun (conquer the school in under 90 in-game days).
Players assume the role of a student returning to school or navigating a new academic year, where choices influence relationship paths and scene unlocks.
High School Master is a popular indie adult visual novel that incorporates sandbox and role-playing game (RPG) elements. Developed by Pervy Bunny Games, it has garnered a significant following due to its distinct art style, extensive character roster, and open-world exploration mechanics.
