This level is one of the easiest levels in the entire game to gain 'A Breath of Fresh Nothing', where you leave the tunnel, float up towards empty space, and somehow return to the tunnel, and land safely.
Using the Skater, you can constantly hit the crumbling tiles and reach the end of the level. With the Runner, just follow the level. Use the Ice Skater, if you have him, the same way you would use the Skater.
Or you could the Runner and just play normally, or float out of the tunnel and return. You will have skipped quite a bit of the level by then.
The A Breath of Fresh Nothing achievement can be done very easily on this level. 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.
