Introduction[]
This is Level 6 of the New Tunnel in Run 3.
Suggested Characters: 
Note: In this tunnel, since you can only use the Duplicator and the Child in this tunnel at first, so the character suggestion's choices will only be the Duplicator and the Child.
Gameplay[]
In this level, the Child is very useful since he can float to far places, such as a platform that is far away. But using him may be a little bit risky, since the platforms are only wide one tile, making landing a bit tricky. Fortunately, there are quite a number of walls in this level, so you can decide to land on a wall if you are going to fall out of the tunnel. The number of sides make it a little annoying to intercept the jump, but aside from that it should be quite straightforward.
Using the Duplicator can be great too. You can try to keep jumping off duplicates in the air, if the spawning frequency of the duplicates is high. Then you will soon keep jumping in midair till the end of this level.
