This level is a copy of level 25 as played by the Runner, and has a bunch of platforms until the end. They are not so small, so this is not as hard as Level 17. However, you still cannot catch onto the sides of the boxes, so this is not a cake walk. If you can judge how far the Skater will jump, you should have no problem completing this.
To get the bonus, you need to go right and jump right at the start of the level. Fall down, then jump onto the bottom of the next platform. You should be on top of the whole level. If you fall, you have to redo this level, because the bonus is at the top near the end of the level. Simply jump from platform to platform until you reach the end.
This level is an exact copy of level 25 for the Runner, named Forth and Back. However, because of the Skater's long jump, you do not need to go back and forth to beat this level like you do with the Runner.
