I will build a playable unity game prototype with custom mechanics


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.
