This is level 5 of the N-Tunnel.
The best possible character for this level is the Skier (the Runner's winter costume) due to her lower speed. As you can see from the picture, you require consecutive short jumps in different directions. If you haven't beaten the Winter Games, you can buy the costume in the shop for 500 power cells, or you could use the Runner, but this is slightly harder. There are many twists and turns you have to make to beat this level.
