This is level 3 of the N-Tunnel.
Despite being quite difficult, you could use all three characters. The Runner doesn't really have much of a strategy. Just play with the level, and remember that you can quickly change gravity and land on what was once the roof.
The Student is probably just the easy way out. Flipping midair gets you a decent way through the level. You are also able to able to reach the roof of the level.
The Skater is easy to use once you understand the concept. Take advantage of the slow conveyors and keep moving where the tiles take you. If you keep reaching the end of the platform and fall off, jump. It will help set you back a little on the platform.
