About this gig

Bring your game idea to life.

If you have a game concept but don't know how to code it, I will build a functional, playable prototype in Unity. I focus on making mechanics work so you can test your gameplay loop immediately.

What I can build for you:

  • Player movement and controller systems (2D / 3D)
  • Core gameplay mechanics (combat, inventory, interactions, etc.)
  • Modular and ready-to-use C# scripts
  • Grey-box level prototypes to test game feel

How we work:

  1. You send me a brief description of your game idea or mechanics.
  2. I build the prototype using simple shapes (greyboxing) to focus purely on gameplay.
  3. I deliver the functional Unity project or executable.


Please message me before placing an order so we can discuss your project scope and requirements.
