Love the ability to get into this piece of music. Give it a shot--its challenging for sure!
I encountered one bug. Once I went into practice mode, tried it briefly, then attempted to go back to medium mode, but it was stuck in practice mode. A restart seemed to fix the problem.
I would love it if this app presented the part in standard notation (as an option). Would be way easier (as a practicing musician).
Lastly, I shared my results a couple times on Facebook, and challenged my friends to beat my score. They had no clue what game it was. Are you kidding me? I share my result on fb and the post gives NO indication what app it is? Devs--that is crazy. Crazy. CRAZY.
