I built a replay rendering engine from scratch using the replay files and Claude Code.

The replay files contain sampled position coordinates and commands that the player inputs. So I built an isometric view using the map and overlayed unit icons over the map, then interpolated the positions that units move in over time.

I also extracted additional metrics from the game data as well - some are derived on top of other metrics.

Finally, I pass all this context into a LLM for it to critique gameplay and offer strengths and improvements per player.

It's not perfect, but a good starting point to iterate and improve

Let me know what you think!
