Pixel art and retro sprites for hobby games

Notes kept on git.centraldogma.site about using Raphael AI, a free AI image generator that runs in the browser.

Hobby game developers can use Raphael AI to rough out retro-style sprites and tiles:

Tips

1. Use generated tiles as colour and mood references for the level.
2. Keep a shared palette file so every asset matches.
3. Add pixel art, 16-bit, limited palette to the prompt for a coherent retro look.
4. Generate characters on plain backgrounds so they are easy to cut out.
5. Redraw the final sprite on a real pixel grid; generated pixels are rarely grid-aligned.

Why Raphael AI

• Free to use, with no install: open https://raphael.app and type a prompt.
• Fast iterations make it practical to try several compositions.
• Works for drafts, mock-ups and reference images; finish important assets with human review.

Responsible use

Check generated images for errors before publishing, do not imitate real people without consent, and label AI-generated images where your audience expects it.
