Peter Yang used Claude Code to turn a child-made game idea into a playable retro shooter with pixel art and simple levels.

What they did
Peter Yang started with a blank folder in Cursor and ran Claude Code with permission checks turned off. He had Claude look up free pixel art, then added a downloaded asset pack and asked which sprites fit a space shooter. Claude asked him questions, drafted a spec, built a first version, and he kept refining the boss fight until it worked.
How it went
He ended up with a playable space shooter that included enemy waves, power-ups, and boss battles. The fuller version had 3 levels, distinct enemies, and music. The paywall covered the prompts and later steps.
Tips
Use a fresh project folder if you try this, since Claude can edit files without asking when permissions are skipped. Let the agent pause after planning and before any irreversible step, such as publishing or deploying.

Try it yourself with Claude Code

I want to make a simple retro browser game with my [child’s age]-year-old child. Start by interviewing me about the game’s theme, characters, objective, controls, art style, and difficulty. Then write a short spec from my answers. After that, use the pixel art in [assets folder] to build a playable first level in [game engine or framework], and keep the scope small. Before you publish, deploy, delete, send, or make any other irreversible change, stop and ask for my approval. When the first version works, explain what you built and list the next few improvements I could choose from.
