This is level 1 of the W-Tunnel.
The platforms are all quite big with ramps, but as the Skater, when the next platform is tiny, jump early so you don't overshoot and fall into the gaps. In other cases, you can use the ramps. After all, ramps convert speed into jump height. Guess who benefits most?
But you can also use the Runner too. Her high jump can avoid overshooting and run into the gaps, which can be helpful and can let you pass the level securely.
