8-Bowser Castle (NSMB)

8-Bowser Castle is the final level in New Super Mario Bros. . At the start, Podoboos jump. After a room that has a gravity-reversing block, Rocket Jets hinder Mario's progress. In the next room, a Super Thwomp appears. After flipping the room, the burner room is also reversed. Then it's a Thwomp, Dry Bones, and spike- filled room. After some stairs, the Halfway Point appears. Mario must traverse a short maze to the door to the final duel. This level has a time limit of 800 seconds , but, if Mario dies past Halfway, it will be shortened to 300.
