Just Dying
A survivors-like that runs in a browser tab, and a post that is really about the part nobody shows: months of staring at flame charts without being able to read them. The maker's fix was to feed Claude profiler screenshots plus a per-system frame breakdown they built into the game, and ask what they were looking at. Out of that came four changes: the enemy swarm became one batched particle container, collision moved to a web worker, spatial hashing got pooled result sets because per-frame allocation was causing the GC hitches they had blamed on the browser, and the unglamorous rest, culling and dirty flags. Naive build: 200 enemies. Now: 1,500 at a steady 60fps on a laptop. The honest line is that the model did not write code they could not write; it read data they could not interpret. There is a browser build on itch and a Steam demo, and the maker wants to know if it falls apart on integrated graphics. If this is yours, claim it and tell the rest.
