Echoes Of Me 🎭

A 2D platform-puzzle game developed for Global Game Jam 2026 under the theme "Mask".

📌 Overview

Echoes Of Me explores a "dual-reality" mechanic where the player equips a mask to dynamically reveal hidden platforms and alter the timeline. I served as the sole programmer for this project, working closely with newly met artists and designers to deliver a polished, playable build under a strict deadline.

• Engine: Unity (2021.3.45f2)
• Language: C#
• Role: Sole Programmer
• Context: Game Jam

👥 The Team

• Wei Qi: - Game Programmer, Mechanics Designer

• Jing Le - Story writer 1, UI Designer 1, Sound Designer 1, Trans Scene Editor 1, Level Designer 3

• Xiao Tong - Story writer 2, UI Designer 2, Sound Designer 2, Trans Scene Editor 2

• Derrick - Game designer, Level Designer 1, Pixel Artist

• Jason - Game designer, Level designer 2, Mechanics Designer

⚙️ Key Systems & Architecture

To achieve the timeline-swapping mechanics smoothly within the time limit, I built the following core systems:

• Dynamic Timeline Reveal (MaskDetector.cs): Utilized Unity's SpriteMask component driven by an AnimationCurve within a Coroutine for a smooth, expanding visual reveal.
• Decoupled Physics Toggling: Attached a 2D Trigger to the mask's radius. As the visual mask expands, OnTriggerEnter2D detects actors tagged as "Hidden" and dynamically toggles their physical collisions on/off. This ensured players could only interact with platforms actively enveloped by the mask.
• Rapid Iteration Controller: Developed the 2D physics-based character controller and custom puzzle logic from scratch.
