Ideas on expanding the star system and incorporating a spaced repetition
For example. We get gold stars for completing the song part my part. Yet there's no star award for getting perfect all the way through. Maybe we should add a part where if you can play through the whole song perfectly, not only will you get gold stars, but you get like a star medal or something.
Also, this I believe is especially true for the workout sections. Scales, chords, ect.. There should be some sort of spaced repetition for these. These are the kind of things that do need to be memorized, and it would be cool to see the system detect when you need to go over it again. That way it could space it out over time to get into your long term memory.
Also, there should be an option to where you can disable the music notes on screen so you can see that not only can you play it, but have it memorized at the same time.
