Pros: Great to develop dexterity to switch finger positions, chords, and find way around fretboard.
Cons: Only 5 attempts given in Riff repeater. Have to push many buttons to get back & try again.
The game adjusts to your ability, keeping it challenging without becoming infuriating/frustrating. Teaches a few chords, but main thing is developing finger strength & dexterity while having a lot of fun playing music. Mini-games help to develop skills beyond plucking the strings.
