48 prompts, 1,000 reasoning steps: dev builds 7,342-line zero-dependency game with Gemini 4 Argon

Developer @TheBalkanHacker used Gemini 4 Argon (unverified name) with the Antigravity TUI to produce a fully playable Lemmings-inspired cozy farming sim in a browser. Just 48 user prompts drove roughly 1,000 agent reasoning steps and 1,125 tool calls.
The output is a single-file, zero-dependency vanilla JS/Canvas game (terrarium.html) totaling 7,342 lines: a 250×154 cellular-automata soil grid, subsurface hydrology, cavern drip, 4-stage flora erosion, and 14 autonomous lemmings that dig tunnels and mine. The author called it an impressive showing for the model.
