Episode 1 · GPT-6 Astra beats Geometry Dash first levels with all coins (2026-09-18, 3 posts)
AI agent Astra cleared Geometry Dash's first four levels, collecting all coins to unlock Clubstep, and grabbed all 3 coins in Dry Out on its first recorded attempt; a separate RL agent achieved the same feat.

Episode 2 · GPT-6 agent "Astra" clears Geometry Dash demon level Clubstep, method open-sourced (2026-09-18, 5 posts)
On September 18–19, developer imjustnewatai posted repeatedly about GPT-6 agent "Astra" beating the Geometry Dash demon level Clubstep, open-sourcing the full code and method.
Confirmed
- Astra plays in a state-aware, tool-assisted (TAS-style) manner: it uses pauses for planning, ordinary keyboard input, and the game's native collision and damage rules, with no memory editing or physics-modifying scripts; edits only removed planning pauses, with a full-run video for verification.
- The clear happened in normal mode (damage and collisions fully enabled). Recording took 7 attempts: 2 deaths, 4 manual resets, and one clean clear.
- Coins earned from four easier levels unlocked Clubstep; this is level 1 of a six-demon challenge, with Theory of Everything next.
- The complete code and method have been open-sourced.
Why it matters
- The author frames it as a tool-assisted experiment rather than an unassisted playthrough, but it demonstrates the capability frontier of LLM agents in fast, high-precision reaction games when combined with state awareness and pause-based planning, while remaining fully reproducible with original game physics.
