Featured Project
Cure The Dead
An open-world survival game built entirely in Unity 6 & C# — designed, programmed and animated from the ground up.
▶ Live gameplay capture
Cure The Dead is my flagship title — a systems-driven open-world survival game. I architected and built every core system from scratch: a living town of AI-driven NPCs, a working delivery economy, interactive doors and props, character animation, and a hand-crafted, atmospheric open world.
- Living world AI — NPCs powered by Behaviour Designer trees & Unity NavMesh, with spawners that populate the town dynamically.
- Delivery system — a drivable delivery truck with cargo, routes and merchant drop-offs.
- Interaction systems — modular door/animator scripts and usable props across the map.
- Open-world design — terrain, lighting and environment art tuned for mood and performance.
Systems I built for it
Delivery System
A drivable delivery truck with cargo crates, routes and merchant interactions driving the in-game economy.
Interaction Systems
Reusable door & prop interaction scripts with animation hooks, wired across every building in the map.
Character Animation
Humanoid character setup, animator controllers and motion tuned for responsive, believable movement.
Open-World Scene Design
Terrain sculpting, environment art, atmospheric lighting and performance-minded world building.
Clean Architecture
Organised, maintainable project structure — modular scripts, clear folders and reusable components.

About Me
Hi, I'm Phenyo 👋
I'm a self-driven game developer and the creator of Cure The Dead — an open-world survival game built entirely in Unity 6 and C#. I specialise in the systems that make games feel alive: NPC artificial intelligence, behaviour trees and navigation, interactive props, delivery and economy systems, character animation and atmospheric scene design.
I don't just write code — I architect maintainable systems, profile and optimise for performance, and obsess over game feel. Whether you need a single feature built, an existing project rescued, or a full prototype taken from idea to playable build, I bring the same studio-quality care to every contract.
- ✅ Clear, frequent communication
- ✅ On-time, milestone-based delivery
- ✅ Clean, documented & maintainable code
- ✅ Post-delivery support
