This is Level 19 of the Main Tunnel of Run 3. This level is one of the easiest levels in the entire game to gain 'A Breath of Fresh Nothing'.
Suggested Characters: 
Gameplay[]
Using the Skater, you can constantly hit the crumbling tiles and reach the end of the level. With the Runner, just go to a tile you think you could reach easily and jump to it. It is suggested you go onto crumbling tiles but if you do not feel you could make it easily, go onto a normal tile instead.
Achievements[]
The A Breath of Fresh Nothing achievement can be done not very easily on this level. To do this achievement you must leave the tunnel, float up towards empty space, return to the tunnel, and land safely. It awards 100 power cells. It is recommended that you choose the Runner, floating out to the right at the first gap on the right in the picture, and floating in when you have floated upside-down.

Level 19 Walkthrough (Run 3)
In this walkthrough, crumbling tiles were not used just to be safe. Feel free to use them when you are playing this level since it does not increase the difficulty of the level.
