In this level, the ice tiles speed you up, so you can't have a character that jumps too far, or jumps too small. Just about any character makes this level easy, so the suggested ones are entirely random.
The Ice Skater is pretty useful in this level. His speed can increase your chances of defeating this level significantly, only if you know how to use him. Try to keep landing on the platforms. When you jump through a gap, this can prove to be really helpful, although, his low maneuverability may be a problem.
The Lizard is also a good one. Due to its big jump, you can beat this level like a master.
The Pastafarian has a bridge, so you can sandbox this level with her.
A cutscene is featured on this level. More information on this cutscene can be seen here.
Planet Stolen Edit
When you start this level, a cutscene will occur. The official page can be found here. The Duplicator, appalled, says to the Runner that the Planet is gone. The Runner doesn't seem to care because she knows it will come back. The Duplicator accuses the Runner of stealing the Planet. The Runner ignores him entirely and tells him to help her map out the U-Tunnel.
