| This level is a major plot point!
This level is a major level in the game. After you finish the level, you may be able to access other characters, minigames, and tunnels. Most of them also include a cutscene.
| You get an achievement!
This level has one or more achievements. The achievements are listed on the level infobox.
This level has a mixture of rings and long and tiny platforms. The Skater is the best character for this level as he can handle the long jumps. Or you could use the Student, who can change gravity when necessary, which is normally tricky, since the number of sides is only five, which is quite small, not to mention the little room for error with the low headroom.
If you use the Skater, use long jumps and you will be able to speed through the level through the gaps, and just be careful that your speed is not quick enough. You can even consider to beat the last level with him and speed him up completely by letting him keep skating through the last level, so you will get some extra speed before you start this level, giving you a head start. The last level wasn't even that hard anyway, so give it a shot.
The Achievement Frictionless features in this level. You have to use the Skier to reach the conveyors in this level, but you have to keep your skis fully inside the tunnel. What you must do is go back to N-6, choose the Skier, and near the end, touch the fast conveyors on the right. When you are in the gap between the levels, change gravity so that you are on the same side as the first set of conveyors. Then jump towards them and you have got the achievement!
