NO THING

It's one of the easier levels and it introduces the green orbs which speed you up instead of slowing you down. The first one is more or less thrown into your face. Other than that one avoid them here. While following the path, choose the sides with orange orbs, but try to not take them all, because you will backtrack here and need them then. (In addition, while I don't think the layout here allows for it to actually happen, collecting an orange orb when you are too slow will cause you to run backwards which you do not want to happen.)

You can just follow the path, but there is a shortcut that makes the track easier to handle. You will soon come to a bridge and at its end, move left onto the track beside yours. It leads into a dead end loop you normally would arrive at later, but that's okay. You will now backtrack the whole level and run on some more.

When you reach the bridge you stepped off before, get onto the circular area to the left to collect the three orbs there, then go onto the bridge. From here on, it will be very obvious where to go. Try to avoid the green and collect any remaining orange orbs. The rest of the track is pretty easy to run.
