Introduction[]
This is Level 3 of the D-Tunnel, which is later renamed The Crystal Gallery in Run 3.
Suggested Characters: 
Gameplay[]
Just like the previous two levels, there isn't too much of a strategy. You can just play as the Lizard, as it goes slowly and you have an opportunity to change walls if something goes wrong or there are no platforms in front of you.
You could always cheat death as the Pastafarian - up to a certain point, though, because you will have to jump eventually. But still, you can skip a large portion of the level by walking the light bridge, just like what happened in level 1 of this tunnel. This surely makes this level considerably easier.
The Student would make it considerably easy since you can just flip around a few times and land. You can maintain in midair for an extended period of time that can let you pass a large portion of this level without the need to really navigate through the platforms. Though, you have to really be prepared for the unexpected, since the Student can easily flip around if you float up too high, and this sudden change of environment may make you lose the level easily. Beware of overshooting landing platforms as well, since this can occur quite commonly if you are using the Student.

Playing With Fire[]
The Skater meets up with the Child in The Crystal Gallery, part 3. The Child shows off some candy he found, to which the Skater asks if he could try one. The Child gladly offers one, saying he doesn't need them, and asks if the Skater likes candy. The Skater doesn't mind them and says you have to eat something at least, to which the Child goes on a little mini-rant about diets.
The Skater apologizes for setting the mood down, and insists they talk about something fun, which reminds the Child that they can instead burn the candy. The Skater asks if he can see it as long as the Child is okay with it. The Child happily obliges, saying that he has nothing else to use it for.
