Behind all the intimidating ice tiles and rings, this level honestly isn't that hard. If you ignore all of the rings in this level, you will see just a bunch of long icy platforms that would be easy to land on.
The Skater would be the best character for this level because his speed would make full use out of the ramps. Try to always use the ramps, so you can fly up the ramps and land on a distant platform. Ignore the rings in this level because they are harder to land on and require more jump mastery to accomplish, especially with the Skater.
If you wish, can beat this level with the Runner with the same gameplay as with the Skater. Just aim for the long rectangular platforms all the way to the end of the level. The ramps may not propel you as far as they would if you were playing as the Skater, so you may want to ignore the ramps too.
If you are up for a challenge, try beating this level without jumping! Follow the ramps around the tunnel until you reach the end. However, not all routes will work, so you can beat this challenge through trial and error.
