About this gig

Have a great game idea but need a playable prototype to prove it works?


Turning an idea into a functional prototype can be difficult when gameplay systems, mechanics, controls, and interactions all need to work together. Ill transform your concept into a playable Unity prototype that you can test, demonstrate, or use for further development.


I can build:-

  • Custom gameplay mechanics
  • Player controllers & movement
  • Combat, interaction & ability systems
  • Enemy AI and basic behaviors
  • Inventory, health & progression systems
  • Interactive environments
  • Basic Unity UI and HUD
  • Gameplay VFX and feedback
  • Prototype levels and scenes
  • PC or mobile controls
  • Clean, organized Unity project structure


My goal is to create a functional and testable prototype, not just a visual mockup.

Whether you're developing an indie game, multiplayer concept, mobile game, RPG, FPS, simulator, platformer, or experimental game, I can help turn your idea into something playable.


Send me your game concept, mechanics, references, or design document, and let's build your prototype.
