The full story
A maker ported StudioIgor's Unity real-time strategy game to the web with Claude (Opus 5.5) and made it controllable with in-game text prompts. Each worker, soldier and the enemy commander asks a classifier called JEV, through OpenRouter, to pick from a short list of typed options such as gather, attack or wait; the engine only checks the choice is still legal.
The demo is a static GitHub page and needs a local copy of the original art assets. The poster warns a full game can cost from 25 cents to $5 in API calls.
