I was playing Bonk 3 with my 9 year-old, who is a novice with console games. I guess we didn't make it too far yet, but so far it's been OK (but definitely would be worse if she didn't have my guidance).
On a side-note: it's weird to watch someone who is rough with even the simplest platforming moves: jump in place, run and jump, attacking while stationary versus in motion, etc.
