This is level 44 of the Main Tunnel.
In this level, the gaps are not too large, so the Runner should be the most suitable choice. If you use the Lizard, you may jump too far away, and end up in the void of space. So be careful. The crumbling tiles are not a large threat in this level, due to the fact that you need to jump, quick and fast, right after you land on a platform most of the time. Overall, this level is slightly easier than the last one. If you can beat the last level with ease, this level shouldn't give you a hard time.
