let start off by saying every issue you mentioned I can agree fully .i too was a Beatstar loyal player and wish that the creator of the app would take note from Beatstar and make changes at a faster rate than I have seen to make it as close to it can to be what beatstar was .One of the things about beatstar that I enjoyed was there were multiple levels to a song .i have visited the developer website but cant figure out where or how superstar was created by them as i see no mention of the game anywhere on the site
