Jaehyuk Choi
I create immersive worlds and interactive experiences across PC, mobile, and XR — from a bullet-time shooter shipped on Steam to VR defense levels and AI-driven educational games. I design systems, levels and combat, then build and playtest them until they feel right.
Background
I’m Jaehyuk, a game designer at USC who loves turning ideas into playable experiences. From designing combat systems and levels to building interactive experiences across PC, mobile, VR, and AR, I enjoy experimenting, solving design challenges, and refining games through playtesting.
