Super Paper Mario

Super Paper Mario is a RPG-styled platformer developed by Intelligent Systems and published by Nintendo for the Wii. The gameplay is similar to the classic Super Mario games, but with the aesthetic qualities of the Paper Mario series, RPG-like elements like character dialogue and puzzles, and a blend of 2D and 3D platforming. The player starts out with only Mario, but unlocks Princess Peach, Luigi, and even Bowser through the game, and can change between them at any time.

The game was originally planned for the Nintendo GameCube in 2006, but Nintendo changed it to a Wii release due to declining GameCube sales.

Pal Pill
The little pals are only visible when you're moving or jumping. If you stand still they become invisible, until you start moving again.

Z-Order Glitch
Heart Container sprites are not ordered appropriately and layer on top of the screen. To prevent this, use the OpenGL video backend.
