This is level 14 of the Low Power Tunnel.
Similar to Low Power Tunnel, part 6, in this level, there are also dimly-lit power tiles that connect to each platform. They are entirely made up of power tiles, and since there aren't any crumbling tiles in this level, you can step on them if you want to.
Treat this level as a common snake level. Just jump high and find a place to land. As for the Pastafarian, you can walk on the light bridge, but avoid jumping on it, or else the light bridge would "break" and you can't use it again unless you beat or fail this level.
A side tunnel (New Tunnel) can be seen in this level, but it is proved that you can only unlock it after you beat the next level. So, start working and beat this and the next level to unlock it!
