Gameplay
This level is almost entirely made up of crumbling tiles, but don't worry, they don't all connect as one big chain. Just figure out which ones are linked, and move to the next set. A fast character would also be good. But whatever you do, do not jump the second you hit a set of crumbling tiles, given that the crumbling tile chains are still quite long.
But if jumping just seems more effective, and floating and hoping for the best, use the Child, as the effect won't be as destructive, and the tiles won't fall as fast.
Overall, this level isn't a very big problem, and you should pass quite fast.
