Is there any way to see the requirements for each level? More specifically on levels like Polylylyrimshot where there are no rankings?

非常に横暴な要望で申し訳ございませんが、6本指以上の練習機能もあると非常にうれしいです

Could we please get some other options as far as the type of sound that is played on each beat? the sustained piano bleeds together with the other notes so hard that is insanely difficult to make anything out once it gets more complicated. Would really like to see some kind of tone that has significantly less sustain on it....
