Gameplay
This level should be more suitable for the Runner than the Skater. It is because she is much slower than the Skater and is better for avoid the crumbling tiles. If you are able to avoid the crumbling tiles, this level is a lot easier.
While using the Runner, try to keep in midair for a long time. When you land, try to land on normal tiles. If there aren't any normal tiles in front of you, try to look and land on the wall.
If you are a beginner at the game, the Child can be more suitable as he can walk on crumbling tiles without them falling. In fact, doing this means that you can beat the level easily without jumping.
