About
This clone's own README dates the original Lose Your Marbles to 1995. It was distributed as part of Sega's Sega Smash Pack compilation series (Windows, Dreamcast, and Game Boy Advance, 1999–2002), which mainly gathered games originally released for the Sega Genesis. This is a browser-based remake of the 1995 Sega marble-matching game Lose Your Marbles, built with the Phaser JavaScript game framework.
Getting started
It's playable directly in a browser via the project's current hosted demo link (an earlier hosting link mentioned in the README is no longer available).
