This is level 44 of the Main tunnel.
In this level, since the gaps are no too large, so Runner should be a more suitable choice. If you use the Lizard, you may jump too far away, and ending 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.
