SCRIPT-8 is a JavaScript-based (React + Redux) fantasy computer for making, sharing, and playing tiny retro-looking games (called cassettes). It's free, browser-based, and open-source. Cassettes are written in JavaScript.

SCRIPT-8 is designed to encourage play — the kind of wonder-filled play children experience as they explore and learn about the world. In order to support this goal, everything in SCRIPT-8 has immediate feedback. It is what some call a "livecoding" environment.

It features:

• a code editor where the game changes as you type
  

• a slider to help you tweak numbers without typing
  

• a time-traveling tool so you can pause and rewind
  

• buttons that show a character's past and future paths
  

• the ability to combine all the above so you can manipulate time
  

• a sprite editor where the game instantly displays your edits
  

• a map editor where changes alter the game's behavior, in real-time
  

• a music editor where you create phrases, group them into chains, and turn those into songs
  

Each cassette is recorded to a URL you can share with anyone.

Play cassettes with a keyboard or gamepad.

You can inspect any cassette's contents (even if it's not yours), change the code, art, or music, and record it to a different cassette — a new version.

SCRIPT-8 is heavily influenced by Bret Victor's ideas (specifically Inventing on principle and Learnable programming) and Joseph White's PICO-8 (the best of all fantasy consoles).

If you have any questions, come join us on the Fantasy Consoles discord server, a friendly place to chat about these sophisticated, cutting-edge computers. The server has a dedicated SCRIPT-8 room.
