8-Bowser Castle (NSMB)
This place is TOUGH! At the start, Podoboos jump. After a room that has a gravity-reversing block, Burners roam the place. In the next, a Super Thwomp appears. After flipping the room, the burner room is also reversed. Oh, and a Dry Bones appears. If you hit a switch, a inaccessable platform will appear. You leave. Then it's a Thwomp, Dry Bones, and spike- filled room. After rotating it, you have access to a Star Coin. After departing, you can see that, if you hit the switch, get a Star Coin. After some stairs, the Halfway Point appears. After hopping over Poboboos, a Firebar, and lava while taking correct paths(if you don't, you need to take the correct one because the room will repeat), you can smash some blocks for a Star Coin. Then you will see the door to the final duel. This level has a time limit of 800 sec., but, if you die past Halfway, it will be shortened to 300.
