This is level 7 of The Crystal Gallery.
As the Runner, just do what you normally do. If you look on the Runner's page, she's quite an all-rounder, so I would say she would work. The only difficulty may be judging between long and short jumps, and where to land.
The same goes for the Lizard, except it is slower and you can touch walls and change gravity if it all goes wrong. The Lizard jumps high, but not necessarily far, so try to jump off at the end of the platform you are on.
You could also use the Pastafarian, where... umm... Seriously, just try it. It will be satisfying to see the level's end just appear almost effortlessly.
