	Various Gameplay Hints...

Complete level 1. When the level completion summary appears, tap "Change Player" then "Continue" to keep going. You can alternate players as many times as desired to receive more coins each time.

You can grind underneath rails as well as on top of them.

Watch out for the white signs telling you that you need to switch direction, and make sure you adjust your drop accordingly.

Just because there's no jump sign, doesn't mean you can't throw in a leap here and there to reach other coins.
