AI Tools Used
Claude (Anthropic) — used for essentially all of it: the game design, all the JavaScript (the visibility-polygon shadow solver, the fixed-timestep loop, the WebAudio synth), the store text, and the cover art, which is not a generated image but a purpose-composed scene rendered by the game's own canvas shadow renderer with the lettering typeset over it.

No image, audio or video generation model was used anywhere. There are zero asset files in the build — all 51 KB of it is code, so every visual is drawn at runtime and every sound is synthesised from oscillators and filtered noise.

Balance was tuned against measurements rather than vibes: an instrumented autoplayer ran the game headlessly, and two real bugs came out of it. Burn fell off as heat-squared while lit enemies were slowed to a crawl, so the light was pinning them exactly where it could not hurt them; and once that was fixed a plain dodging bot survived the full test cap three times out of three, which showed difficulty had stopped climbing.
