About the Project

Knock Knock is Prototype #2 in a short horror game series where I explore concepts in 1–3 days, aiming for quick, minimum viable builds. More of a "demo reel" than a full game, it’s inspired by the Mandela Catalogue and the “fake humans” genre. Built in under three days with some voice help from friends, it’s part of a batch I’ll eventually refine into a full game based on feedback — possibly even my first Steam release.

Development Process

The development focused on creating immersive systems that build psychological tension. Key implementations include:

• A dynamic character system with safe and unsafe visitors.
• Peephole mechanics with smooth camera transitions and FOV animation.
• An anxiety system that distorts audio based on player decisions.
• Realistic movement and footstep systems.
• Voice line queueing and character management.

Technical Challenges

• Creating a believable risk/reward system around the peephole mechanic.
• Implementing subtle audio distortion that scales with player anxiety.
• Designing a character system that manages different visitor types and their voice lines.
• Building smooth transitions between normal view and peephole view.
• Creating appropriate feedback systems for player actions

What I Learned

• Character and audio management in Unity.
• Camera manipulation and smooth transitions.
• Player feedback systems through audio and visual cues.
• First-person controller refinement.
• Creating effective psychological horror through game mechanics.
• State management for gameplay elements.
