I really liked DominoSwedish and that Felix and team were building CEFL level based courses for it. I'm sad to see it go. Are there any plans to bring it back?

It is offline but you can try his old Udemy course: https://www.udemy.com/course/swedish-made-easy/

Those were great, but Felix also had some new content he had started adding to dominoswedish that went further than his classes with Shien
