Esther Li

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.

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.

Managed multidisciplinary production schedules and task priorities across multiple projects. Coordinated external partners and creative deliverables, translated client/project requirements and feedback into actionable tasks, and maintained communication between clients and production teams. Reviewed deliverables at project checkpoints for completeness and quality before client delivery.
