Demo links are broken (GitHub Pages returns 404)

[mdkstudioslz]

Problem

All demo/game links are returning a GitHub Pages 404 page.

Example:
https://opusgamelabs.github.io/game-creator/crowd-dash/

Expected behavior

The selected game demo should open normally.

Current behavior

GitHub Pages returns:
"There isn't a GitHub Pages site here."

Possible cause

Looks like the routes or GitHub Pages paths are incorrect for deployed demos.
