imjustnewatai · x · 2026-09-19
A tool-assisted agent called Astra, powered by GPT-6, cleared the Geometry Dash demon level Jumper with all 3 hidden coins, unlocking Theory of Everything 2 (Clubstep was already down). The full run is shown at normal speed with 14 strategy captions. On attempt 2 the planner missed a lower boundary during an upside-down jump and died at 92.59%; Astra added a rule, replayed its own inputs to 92.38%, and waited for a higher ceiling before jumping — clearing it on attempt 3.
