a slower paced level from colors

rewarding players with speed for passing platforming sections? check

it looks like this game will have a mix between high speed and low speed levels, which is great

DAT SOUNDTRACK

also there's a red coin system
mario, anyone?

Sonic and the Secret Rings did it too. Each stage had a fiery red ring to find. But in this case it's 5 or 6, dunno.
