Hello. I probably should've kept you all updated on the mod awhile ago. I apologize for ignoring this page.
The mod is not dead and is still being worked on. Right now, we are on 13/19 chambers. Although the 13 of the chambers are playable, we still have to add some extra polish to them.
Remember that chambers doesn't equal levels in general so it may take a bit longer even after finishing the test chambers.
Good to hear!
