A Reddit user says they built a playable 3D side-scrolling platformer almost entirely with AI prompts, with no manually written code.
- Model used: Atomos
- Prompts so far: 4
- Build time: less than 1 day
- Token spend: about $20
- The game reportedly includes 6 biomes/zones, multiple levels, and a boss fight
They also shared the prompt and a public play link, and said they beat the first version in about 4 hours after 89 deaths. They note the sound effects still need work and invited feedback and workflow questions.
