I don't think they meant re-vamped tutorial. They mean an actual campaign mode where levels need to be completed to go on to the next challenge.

Parkour levels and running would be easy to establish. Set up obstacles and make the player touch an object to win.

I guess the running challenges or parkour challenges can be set-up easily.

I like the idea of using the ninja target level. "Knockdown (x) number of targets." It focuses on movement and attacking, it's pretty balanced.

Maybe a throwing or kicking challenge?
Throwing a ball at a target. Kicking a ball into a goal.
Then increasing the difficulty by shrinking the target and goal sizes. or off-setting them at an angle.

Maybe later on in the parkour challenges, reaching the end goal before a certain number of turn-frames.
