This is the thirteenth level in the Main Tunnel of Run 3.
Preferred choice: Skater
Using the Skater in this level can be very convenient, he is real fast, so he can jump across multiple holes! But you have to keep track for his momentum. If you want to dodge the holes while keep getting momentum, you can walk diagonally, avoiding the holes. If you change gravity, you won't lose momentum, so changing gravity is also a great choice.
When you jump, look for your landing place. If you can't find one, try to land on a wall. This way you can change gravity while in the air! Isn't that cool?
