As a member of the 78%, it looks interesting (and I just bought it). However, the video seems to provide the only real tutorial. There needs to be a walk-through in the app (perhaps there is). Also, I'd like to see some sort of visual/tracer feedback as you press the keys (and apparently, you can even able to vibrate them). I don't know if the processor can handle it, but you could use the sound wave in the key itself. But even color changes or a sparkle (users could turn off in preferences). Good luck!
