Build a game like BitLife with Claude Code

A text-based life simulator: age up one year at a time, random life events with choices, stats for health, smarts and happiness and more.

WeekendA working first version in a day or two

The Claude Code prompt

Build an original browser game in the same genre as BitLife: a text-based life simulator. Use your own name, characters, art, sound and levels. Only the general mechanics should feel familiar; do not copy BitLife's name, characters, art, music or level layouts.

Version one should have:
- Age up one year at a time
- Random life events with choices
- Stats for health, smarts and happiness
- Jobs and relationships
- Ending summary

The hard part: Writing lots of events. Generate them with Claude and keep them in JSON.

How to build it:
1. Read this folder first. If it is empty, set up a browser game with Vite, TypeScript and Phaser (or Three.js if it is 3D). Write a short PLAN.md with the game loop, entities, controls and what you are leaving out of version one.
2. Get the core loop playable before anything else: age up one year at a time. Use simple shapes or free placeholder art until it feels good.
3. Add the rest of the mechanics one at a time, keep game rules in pure functions you can unit test, and make it work with both keyboard and touch.
4. Add a start screen, game over, score and a saved best score in localStorage, plus sound effects you generate or that are free to use.
5. Run it, play it, tune the difficulty, fix what breaks, and finish with a summary and how to deploy it as a static site.

Paste it into Claude Code in an empty folder. It plans first, so read PLAN.md and steer before it starts building.

Version one

  • Age up one year at a time
  • Random life events with choices
  • Stats for health, smarts and happiness
  • Jobs and relationships
  • Ending summary

The hard part

Writing lots of events. Generate them with Claude and keep them in JSON.

Make it yours: original name, characters, art and levels. Familiar mechanics are fine; BitLife's assets are not.
