Developed in the style of games like Happy Wheels or Mutilate a Doll , Happy Room places the player in a sterile, clinical laboratory setting. The objective is seemingly simple: cause as much damage as possible. Players are given access to a wide arsenal of weaponry, ranging from simple firearms and explosives to sci-fi gadgets like portals, lasers, and black holes.

The game features violence. While it is stylized and features dummies rather than humans, there is blood (though often adjustable or toggleable) and dismemberment. It is rated Teen or equivalent. It is not suitable for very young children, but for teenagers, it is generally seen as a cartoonish stress reliever rather than a psychologically harmful experience.

While it seems like mindless violence, there is a strategic layer. To unlock new weapons, players often have to achieve specific milestones of damage. This encourages players to stop spamming grenades and start thinking: How can I maximize the damage with this specific weapon combination? It turns a sandbox into a puzzle game.

In a traditional spreadsheet, KData1 is rows of black text on a white grid. In a happy room, this same data is transformed.
