🛡️ Leif’s Adventure: Netherworld Hero

Full-Cycle Solo Game Development | Unity • Spine • Photoshop

📝 Project Overview

Leif’s Adventure is a story-driven action-adventure inspired by Nordic folklore, developed over a 7-year journey. As a solo developer, I spearheaded the entire production pipeline—transforming a creative vision into a commercially released title on major gaming platforms.

The game features a unique dual-character mechanic (Leif & Ghost), challenging boss fights, and a rich, hand-drawn world that supports both Solo and Co-op play.

🚀 Multi-Platform Success

I personally managed the technical porting, optimization, and rigorous certification processes for a global release. The game is successfully published on:

PlayStation 5 (Sony)

Nintendo Switch

PC (Steam)

🛠️ Technical Expertise & Workflow

🎮 Unity Engine Development

Core Systems: Architected complex C# systems for gameplay mechanics, AI behaviors, and modular UI.

Console Optimization: Fine-tuned performance to meet the specific hardware requirements of the Nintendo Switch and PS5.

Level Design: Designed expansive 2D environments with integrated state-management logic.

🦴 Animation & Rigging (Spine 2D)

Utilized Skeletal Animation in Spine to create fluid, professional-grade character movements.

Implemented advanced animation blending and state machines within Unity to ensure high responsiveness.

Focused on technical animation to enhance combat feel and environmental interaction.

🎨 Visual Arts & Illustration (Photoshop)

Illustrated all in-game assets, backgrounds, and VFX using Adobe Photoshop.

Developed a cohesive, atmospheric art style that defines the game’s identity.

Created custom frame-by-frame animations to complement the Spine skeletal systems.

🏆 Key Milestones

• 7-Year Full-Cycle Production: Managed all stages from prototyping to final Gold Master.
• Console Certification: Successfully navigated Sony (TRC) and Nintendo (Lotcheck) submission processes
• Innovative Mechanics: Integrated a seamless co-op experience and a diverse weapon/stat system.
• Global Launch: Coordinated a multi-platform marketing and release strategy.

“A testament to persistence and technical versatility.”

Leif’s Adventure demonstrates my ability to bridge the gap between high-level art and complex engine architecture.

Platforms: Available now on PS5, Nintendo Switch, and Steam.
