Lexy's Labyrinth

This is a reimplementation of Chip's Challenge®, that puzzle game you might remember from the early 90s (and its long-awaited sequel).

It's free; runs in a browser; has completely new artwork, sounds, and music; comes with hundreds of quality fan-made levels built in; and can load the original levels from a copy of the commercial game!

Documentation is underway on the wiki.

My lawyer is telling me to say this

To be absolutely clear: this is a fan project and is not affiliated with, sponsored by, endorsed by, or in any way approved of by Bridgestone Multimedia Group LLC. Chip's Challenge is a registered trademark of Bridgestone Multimedia Group LLC, and is used here for identification purposes only.

Despite the names, the built-in "Chip's Challenge Level Packs" are community creations and have no relation to the commercial games or their levels.

For developers

It's all static JS; there's no build system. If you want to run it locally, just throw your favorite HTTP server at a checkout and open a browser. (Browsers won't allow XHR from file:/// URLs, alas. If you don't have a favorite HTTP server, try python -m http.server.)

If you have Node installed, you can test the solutions included with the bundled level packs without needing a web browser:

node js/headless/bulktest.mjs

Note that solution playback is still not perfect, so don't be alarmed if you don't get 100% — only if you make a change and something regresses.
