I'm the creator of the bonus levels timer mod and I finally got around to updating it to the latest version of the base game! I probably should have made the competitive patch work but the bonus levels are longer than the base game anyway so it should be fine.

All you have to do to update if (if you've already visited the site) is click on the link in resources, then do CTRL + SHIFT + R to hard reload the site, and it should update to the new version.
