A 2D top-down shooter built in MonoGame on a custom engine. Kim designed and implemented the entire enemy system from scratch.

Built the base Enemy class with screen-edge random spawning and hit detection. Designed the ZombieBoss with 4 distinct bullet-pattern phases — rotating spreads and aimed shots — cycling every 7 seconds with pause intervals. Created Skeleton, Ghost, and all projectile types. Game sends session stats via Socket.IO.

A Unity 3D first-person prototype built around an echolocation mechanic — press Space to emit a particle pulse that reveals the environment.

Owned all enemy logic: state machine architecture, object pooling for performance, and a modular weapon-assignment system that gives each enemy type distinct behaviour. Enemies dynamically equip different weapons, creating varied encounters in the same space.

Mixed-reality experience visualising organisational structures and HR processes, created for the Hogeschool van Amsterdam and Organisation Insights.

Responsible for all UI in the immersive environment — visual effects and every layer of user interaction. Translated complex organisational data into spatial UI elements that users could navigate in mixed reality.

A bullet-hell space shooter set on the moon, built in Unity. Players defend against alien waves using multiple weapons and upgrade paths.

Built all enemy systems — enemy types with distinct attack patterns, spawning logic, and behaviour. The game features dual upgrade systems (offensive and defensive), random meteor hazards, and multiple ranged weapons. Playable on itch.io.
