This is level 61 of the Main Tunnel.
Note: After the Main Tunnel and the Winter Games, we expect you to have obtained the Child. Many levels require him.
This level is quite hard. As the Runner, don't be afraid to go down a little on the crumbling tiles, or you may not land on the next platform.
You could also just keep jumping as the Skater, but remember you can shorten jumps by hitting a wall mid-jump.
Or if you've taken the challenge and beaten the Low-Power Tunnel and obtained the Child, you could just jump in the middle of your current platform to reach the next one. Don't jump at the end or you might overshoot, and since there are a lot of sides, it's not easy to stop the jump.
