This is level 6 of the U-Tunnel.
In this level, the large gaps are frequent, and some of them are even five tiles wide! Therefore, you need to have characters that can jump far away. Skater may be a good choice, but he runs too fast, thus it is difficult to move him sideways. There are also occasional small gaps, so you need to adjust the height of your jump. Therefore, the Lizard is not a suitable choice either. There are even crumbling tiles that will cause you trouble when you land in the platforms. That's why the Child is a great choice. He can run on top of them without making them crumbling, and his jump can lead you to far far away, letting you pass this level while in midair most of the time.
The Student is also excellent in this level, as she can decide how far she needs to jump by floating in the air, and when in need, she can try to land on the platforms in the ceiling, making this level much easier.
The Runner, is all-rounded and therefore, you can use her to solve any problems you meet during this level with ease.
There is an achievement in this level --- Straight Forward. In this achievement, you cannot change gravity , not even a little. Try to use jumps to pass through the gaps in front of you! Your accuracy of your jumps is crucial in this achievement; sometimes your landing place is only one tile large. That's why this achievement is not for beginners.
Notes: If you find your starting place is not good for you, restart the level. If all starting place is not suitable for you either, try to play the last level again, and choose where you want to start this achievement.
