This is level 46 of the Main tunnel.
In this level, the strategy is extremly similar as the last level. But in this level, something changes. There are 16 sides instead of a 4, so changing gravity is much much easier. Also, there are completely crumbling tiles made platforms, so the Runner can't run to the edge of the platforms and jump. In this case, using the Lizard is a more preferable choice. Its superb jump height give you plenty of time to adjust the landing spot, increasing your chances of beating the level.
