Planning Your Horror Game Concept

Start by defining your core gameplay loop. Granny-style games revolve around stealth, puzzle-solving, and escape mechanics. Players must navigate a confined space while avoiding an AI antagonist, collect items to unlock new areas, and ultimately find their way out. The tension comes from limited hiding spots, sound-based detection systems, and the constant threat of being caught.

Essential Game Mechanics

Your AI antagonist needs a patrol system with randomized routes to keep players guessing. Implement a hearing system where dropped items, footsteps, or opening doors trigger the enemy’s attention. Create a simple inventory system for keys, tools, and puzzle pieces. Design multiple escape routes so players have choices, but make each path require specific items or solved puzzles.

Building the Environment

Design a multi-story house or building with interconnected rooms. Each room should serve a purpose – bedrooms for hiding, kitchens for finding tools, basements for major puzzle elements. Use lighting strategically to create atmosphere and guide player movement. Add interactive objects like wardrobes, beds, and cabinets for hiding spots.

Programming the Horror Elements

Sound design drives the fear factor. Add creaking floors, distant footsteps, and sudden audio cues when the antagonist is nearby. Implement a simple health or “lives” system where getting caught resets progress or costs a life. Create jump scares sparingly – they’re most effective when unexpected.

Platform-Specific Development

For Roblox development, use ServerScriptService for the main game logic and ReplicatedStorage for shared assets. Unity developers should focus on NavMesh for AI pathfinding and AudioSource components for 3D sound positioning. Mobile versions need simplified controls and larger interactive areas for touch screens.

Testing and Balancing

Playtest extensively to ensure puzzles aren’t too obscure and the AI isn’t impossibly difficult. The sweet spot is creating tension without frustration. Add difficulty options or hint systems for accessibility. Monitor player behavior to identify areas where people get stuck or lose interest.
