This is level 10 of the Low-power Tunnel.
In this level, there is a long path going to the end. The Power Tiles on top tell you where the path is. However, it wouldn't recommend following those because you may turn a bit too early. The Skater is fast and can finish the level easily. However, if you're scared, use the Runner.
The long path will soon change into completely dark, so changing the screen brightness is not useful. Keep a look at the stars. The places absent of stars means that there are tiles. The long path will first turn you to the left, so at the first part of the level, stay in the left side. But later on, you need to turn to the right side, leading you to the end of the level.
Don't try to jump on those normal tiles. The really small platforms are hard to reach (the easiest way to reach is the Student) and hard to jump on (those who have common sense should know that). Only the most skilled players should be able to do that, but I don't recommend this to anybody.
