The flipping between 2D and 3D worlds in Super Paper Mario are used in tandem with puzzles and challenges that thrive on hidden information or specific set pieces. By building the world in this way, where certain objects are always flat, and others can be 3D when looked at correctly, it expands the environment to accommodate a more measured, patient style of play, while also retaining the platforming sensibilities the game is also going for.
They said my dreams were paper thin,
Tiny, misshapen, small.
“Dream of something with more substance,
Go big, or not at all.”
When dropped, their dreams shattered, but mine?
They soared into the sky
For that’s the joy of paper dreams,
They’re easier to fly.
