I tried the demo of Rayman Legends, and it features one "invaded" level.
Given the higher difficulty (and resulting frustration), I was wondering if such levels are optional or not in the main game.
If they are here only to unlock skins and stuff, it won't matter much to me. If I have to finish such levels to unlock more of the regular ones, it is more problematic.

You don't have to worry about that, these levels are just optional
