A short, psychological horror game developed with Unity for a Game Jam!

Behind the Door is a simple phycological horror game where the player must escape, by advancing through doors. each one that opens, reveals a darker path which ultimately leads to a final choice by the end. Built entirely in Unity using C# and served as my submission for the Pizza Doggy's #3 Game Jam. Here is the Certification

Engine:  Unity

Tools: C#

Project Type: Solo

Duration: 1 Week

Genre: Horror, Thriller

Focus: Timing, Trigger Detection, Audio, Lighting, Door opening and closing logic

• Designed the complete game experience:

1. Built a loop where the player opens a door and transitions seamlessly into another room. 

2. Implemented door mechanics using precise Quaternion and Euler rotations for smooth opening/closing. 

3. Structured level progression to build uncertainty, tension, and player curiosity 

• Developed core systems using Unity’s trigger volumes and C# scripting. 

• Designed multiple endings and separate final levels based on player choice. 

• Challenge: Learning how to pace horror effectively across multiple levels. 

• Solution:

  1. Struggled with understanding the pacing with each level progression

  2. Initially was only using the doors as the changing object within the levels but then realized audio triggers can be used to add more suspense

  3. Solution: After playtesting, found out that audio was the key aspect to creating a horror experience while still keeping the visual design simple, yet effective

• Transitioning from level to level seamlessly and making sure they have a continuous build up

• First-person camera allows the player to immerse themselves with the world 

• Created a loop that the player wants to complete due to mysteries and uncertainties 

• Utilized prefabs in order to re-use certain functionalities within the game with different variables. For example, prefab the door so I would have unique opening and closing speeds

This first game jam taught me that horror isn’t just about mechanics, it’s about pacing, atmosphere, and subtle tension. By iterating on small elements like door speed and angle, I turned a simple hallway into something unsettling and memorable. Building it entirely in C# gave me control, clarity, and a deeper understanding of how design and code work together to shape emotion. This project pushed me beyond programming and into intentional, psychological game design.
