Twice Twice

Twice Twice is a term to describe a troll level design in Super Mario Maker and in other Mario game romhacking where the assets of two or more sections of a level are superficially the same, but upon accessing them, it has different features like pipes and doors that are rendered inaccessible, new hidden traps and enemies, question blocks that yield enemies rather than power-ups, all that are not immediately apparent at first glance.

As such, this might make the player unable to run through the new section using the methods employed for the old one, and cost them time and lives while tracing the new course. Because of its ambivalent nature, the Twice Twice can make the player assume two things: first, that the level sent them to square one (see CP1), or second, that the level is indeed different and that they should tread carefully.

Is this Twice Twice? It better be, because I'm not doing this again!
