Hi everyone, thanks for the feedback!
I'm really glad to hear that the new learning curve feels like an improvement! The new level 5 has now been released. Thank you for your patience.
@Rachellzbth, the new level 6 is coming soon. I encourage you to play songs in the Songs tab in the meantime since you are correct that the old level 6 difficulty level is not appropriate.
@sydnee11, there may be some confusion about the timeline:
Levels 0-3 were released at the end of April. Level 4 was released in May. Level 5 was released now in June. I completely understand that you are eager to move forward, so I am working as quickly as possible. Whenever I release a new level, players may lose their progress or have to unlock the mission again, so I try to test carefully and be sure of the educational value before releasing the changes. The extra testing and revision adds extra time, but I think this is the way to ultimately create the best learning experience for you. I also spend a lot of my time on many "behind-the-scenes" changes and working to add different improvements and features requested on the forum.
Hope this helps! I am working on Level 6 now!
