Grid Games is for people who like fast, tense games, and it's built to feel like an arcade duel rather than a trading terminal. I set the design: two players in the same live market, timing and nerve as the core, and a neon visual style. Claude models wrote most of the code over the course of the project, and I steered the direction and tuning as the game changed. Claude also helped with the performance audit, interrupted-match handling, friend invite links and the login flow.

The early build drew its WebGL scene before the landing page, which slowed the first load, so the landing page now renders first and WebGL loads afterward.

I described each problem by what I saw when I played, then asked for one fix at a time. I tested each change in the browser before moving on.
