experienced not only the white screen bug, but also a bug where it only showed the crowd in the backround. I had to restart and lose all my data. Good concept, just a little under-developed.
It didnt seem like the notes were always on sync with the music, and holding a missed note acts as though you keep pressing it which causes an almost immediate fail. Also i went back to change the keys and there went my save!
Will probably have auto sensitivity in Accelerator 2 :)
