Goal: build a two-player physics skill game where the core loop feels great before anything else is added.

Solution: a Unity 6 (URP) game with physics-driven gameplay and characters animated with motion capture and IK. It's run like a studio project: design and technical docs, a decision log, milestones and a backlog. Playtests are recorded with spoken commentary that's transcribed into timestamped notes with screenshots, so feedback turns straight into fixes.

Impact: 330+ commits and 16 versioned builds in three months, refined playtest by playtest.
