Introduction
This is level 21 of the Low-Power Tunnel.
Suggested Characters: 
Gameplay
The Runner is good for this level because it is all about turning. The groups of lit tiles form an arrow shape, and you move where it points. You don't need to jump. The Lizard may be viable because it is also good at turning.
Good thing is that there are no crumbling tiles in this level, so you can turn round freely. The Pastafarian is also good since she can let you see where the power tiles are more easily.
Overall, this level isn't too hard, and the only roadblock is the darkness.
Trivia
- The groups of three Normal tiles form an arrow, pointing in the direction that the spiral goes in.
