Building a 'race your own ghosts' game with Gemini's Astra agent
LexicalLegend · reddit · 2026-09-14
A Redditor tested Gemini's Astra by having it build a racing game designed to be genuinely replayable. The core concept landed in one shot, with refinements added via follow-up prompts.
- Each completed lap spawns a ghost car replaying your previous lap's path
- Ghosts remember collisions across laps; crashes damage both cars and slow them
- Lapped ghosts are eliminated; you fail if a lap exceeds 15s or bodywork hits 0%
- Ranked by laps completed and fastest total time
