Please unlock the levels – Treble Cat HD - Learn To Read Music Review

Hi, Thank you for your recent updates adding solfege and speeds. I would like you to unlock the levels. Right now there is no way to let the advanced kids play unless I play thru each level myself. Also when the notes are hit, please have the real note sound, not just an arbitrary pitch. Other than that, I enjoy this as a teaching aid.
