 While New Super Mario Bros. is seen in 2D, some of the characters and objects are 3D polygonal renderings on 2D backgrounds, resulting in a 2.5D effect that visually simulates 3D computer graphics. The player can play as either Mario, or his brother, Luigi. Similar to previous Mario games, Mario (or Luigi) can collect coins, stomp on enemies, and break / open blocks. Moves from 3D games featuring Mario reappear in New Super Mario Bros., including the ground pound, triple jump, and wall jump. Enemies from previous games, such as Petey Piranha, are also reintroduced.
