Taiwan-based game designer focused on systems design, gameplay mechanics, and player experience. I design AI behaviors, combat rules, progression, economy, controls, and player-facing feedback across PC and mobile projects, building systems from early prototypes through implementation and iteration in Unity. I define gameplay system rules with clear documentation (GDDs, feature specs, rulesets, state logic, and flowcharts), then validate through playtesting, regression testing, and usability evaluation. My work spans combat, progression/economy, crafting/menus/tutorials, and rhythm gameplay—ensuring edge cases and player readability are handled end-to-end.…Taiwan-based game designer focused on systems design, gameplay mechanics, and player experience.

Work Experience

Game Designer (Part Time) at Indie Games Startup (Remote)

February 1, 2026 - Present

Designed AI behavior systems (investigation, group behavior, trigger priorities, state transitions, and reactions to player actions). Built player-facing combat and feedback systems including aiming behavior, crosshair states, stealth readability, and interaction feedback. Defined system rules, edge cases, values, and expected behavior using paper prototypes, rulesets, state logic, flowcharts, and feature specifications. Analyzed gameplay and comparable titles to identify usability/readability issues and proposed concrete design changes. Worked with Unity to prototype and support implementation and iteration.

Game Designer / Lead Systems Designer at NYFA (Los Angeles)

August 1, 2024 - December 1, 2025

Designed gameplay features and interconnected systems across PC and mobile projects: combat, movement, progression, economy, controls, crafting, and rhythm mechanics. Took features from concept and paper prototypes through documentation, Unity implementation, playtesting, balancing, and iteration. Implemented gameplay features using C# in Unity (inventory, rhythm gameplay, menus, tutorials, and supporting systems). Tested against intended behavior by reproducing bugs, logging tickets with reproduction steps/expected results, and running regression testing after fixes.
