German Level 1 was great - detailed and thorough, moving at a good pace. I have just started Level 2, and it is a different thing entirely, and unfortunately not at all good. It seems to have been botched together from a previous, separate attempt at a course (the numbered Audio lessons are completely different in the lesson plan and in the audio track), and it doesn't follow on from Level 1 in any meaningful way (there’s repetition of stuff we've already covered).
Most disappointing is a dramatic drop in quality of the Language lessons. The grammar explanations are much shorter, and leave gaps and questions unanswered. The lessons on Dative and Genitive are terrible - cursory explanations and patchy examples. Example sentences either display grammatical features which go wholly unexplained in the text; or fail to display the relevant grammar at all. Poorly thought out, and a frustrating contrast to the excellent Level 1.

Hi Tim - At the start of 2020 we revamped all of Rocket Germans Level 1 Language & Culture lessons (the ones you speak highly of!), and were it not for the pandemic we would have also released fully updated Interactive Audio lessons for Level 1 as well (these are probably a month or so away now). Level 2 is going to be revamped in the style of Level 1 soon.
