Stephen John G.

I build responsive, polished gameplay systems in Unity—focused on mechanics, AI, and performance. If your game feels “almost there” but lacks smooth mechanics, smart AI, or optimization—I can help turn it into a complete, playable experience. I’m a mid-level Unity developer with 2+ years of experience, specializing in 2D and 3D gameplay systems using C#. I focus on building mechanics that feel good to play, not just systems that work. 🎮 What I can do for your project: Gameplay mechanics (movement, combat, abilities, physics-based systems) AI systems (state machines, behaviors, enemy logic) Full game systems (core loops, progression, interactions) Optimization (fix FPS drops, improve performance for mobile/PC) UI & animation integration (including Spine) Debugging and fixing broken Unity projects 🚀 Featured Projects 🕸️ Swingfall (Rogue-like 2D Platformer) A unique side-scrolling game built around a physics-based swinging mechanic. Developed custom swinging system using Unity physics Implemented enemy AI (state-based behavior) Integrated VFX, Spine animations, and gameplay systems Focused on responsive movement and performance 🎣 Angler’s Journey A complete game built from scratch, showing my ability to design, implement, and finish core gameplay systems independently. Designed and implemented full gameplay systems independently Built core mechanics without prior professional experience Demonstrates strong problem-solving and self-learning ability 🌌 Take Me To Elysium (Capstone Project) A fully developed game created without AI assistance—pure engineering and research. Built complete system architecture Integrated UI, animations, and VFX Focused on clean implementation using Unity documentation 💡 Why clients work with me: I focus on game feel, not just code I can take a system from idea → fully working feature I understand both technical implementation and player experience I communicate clearly and can work long-term 🤝 Let’s work together I’m open to indie projects, startups, and long-term collaborations. If you need a developer who can build solid gameplay systems and make your game actually feel good, send me a message. *Unity *C# *Game Development *Gameplay Programming *Artificial Intelligence (Game AI) *2D Game Development *3D Game Development *Mobile Game Development *Game Mechanics *Debugging *Performance Optimization *Spine Animation *UI Development (Unity) *Physics Systems *Animation Integration I don’t just write code—I make sure your game feels good to play.
