Common questions

FAQ

I finished Easy — how do I start Hard mode?

Go back to the difficulty selection screen at the start of the game and choose Hard. Easy and Hard run as separate tracks, so selecting Hard begins the harder version of the same 19 challenges.

What is the Scooter Race?

The Scooter Race is a separate activity in the game that awards the Scooter Race Champion Badge to whoever finishes in first place.
