Knock Knock: Room Defense Review

Knock Knock: Room Defense is a horror-themed tower defense strategy roleplaying game from Joy Net Games. Set in haunted schools, hospitals, hotels, streets, and office buildings, it asks you to defend a room against ghosts and monsters by building a hero lineup and upgrading your defenses. The game is presented as fast, 5-minute matches with a gothic chibi visual style and a 12+ content advisory, making it a lighter take on spooky strategy rather than a full horror experience.

• Use the short 5-minute match structure to experiment with different setups without committing to long sessions.
• Choose the room and location theme carefully if you want a different challenge or atmosphere, since the game includes multiple haunted settings.
