Do what the title of the level says. Right Left Space. There's not much that could go wrong. Just be careful: because the speed of the Skater is faster than Runner, so it will be slightly harder than the levels of Runner.
Intense Speed Edit
This level isn't much harder on intense. The only difference is that the level is 2 times faster, meaning all your inputs have to be shorter.
To get the bonus, you must jump on the final raised platform at the end. Also, hold the jump button to jump higher. Otherwise, you may miss the bonus.
The level name is a mirror version of the Runner's first level.
