|This level is a major plot point!
This level is a major level in the game. After you finish the level, you may be able to access other characters, minigames, and tunnels. Most of them also include a cutscene.
For this level, you can either use a character who doesn't trigger the crumbling tiles or someone who can survive even after hitting the one big chain of crumbling tiles. Still, be careful about using the Child. He can still destroy the crumbling tiles by jumping on them. You can use the Student and the Angel as they can make the jump between the normal tile platforms that are far away.
As for the Angel, be careful of the jump you made and be aware of overshooting the platform, which is a very common mistake which players made.
After you clear this level, you will unlock the A-Tunnel. It is 9 levels long.
