Browser Game Starter Kit by Prompt Forge Kits
A downloadable asset pack
You've seen people build games with Cursor and Claude in an afternoon. Then you try it, and 40 prompts later the game is a black screen and the AI keeps "fixing" things that weren't broken.
The Browser Game Starter Kit by Prompt Forge Kits gives you structure, rules for your AI, and a way back when things break. Open the starter in your AI tool, follow a proven prompt sequence for your genre, test after every step, and publish to itch.io when you're done. No game dev experience needed.
What's inside:
- A working Phaser 3 + Vite starter game: a playable platformer with menu, gameplay, game-over scenes and high score; art drawn entirely in code plus a bundled OFL font.
- AI rules files (.cursorrules, CLAUDE.md, AGENTS.md) that keep your AI making small, focused changes.
- Prompt Playbook: 6 genres, 60+ prompts (platformer, top-down roguelite, idle/clicker, endless runner, puzzle, tower defense).
- Grow Your Game chapter, The Fix Loop (debug prompts and common Phaser bugs), and a publishing guide for itch.io, GitHub Pages and Netlify.
- THEME.md visual theme, a one-page Game Design Doc template, and GUIDE.pdf (40+ pages).
- Commercial-use license for the starter code (you may not resell the kit itself).
Requirements: Node.js 18+, Mac, Windows or Linux. Works with Cursor, Claude Code, Windsurf, Copilot; tips for Lovable and Bolt.
A 7-day refund if the kit didn't work for you; may be declined if clearly copied or reused. Free updates included.
