Koichi Hayashida, the director of Super Mario 3D World, recently revealed several details regarding the game in a Wii U Developer Direct.
According to Hayashida, multiplayer works similarly to the New Super Mario Bros. series, in that you can pick up and throw other players. Additionally, each player will receive a score of their progress at the end of the level.
As for the characters, they will perform like their Super Mario Bros. 2 counterparts. Mario is the well rounded character; Luigi is able to jump the highest out of the group; Peach has the ability to float; Toad is the fastest. Additionally, there is one other character that cannot be announced at this time. Also returning from Super Mario Bros. 2, is the ability to pluck and throw objects. This will be used to solve puzzles and pull switches.
New to the series are the cat suit and transparent warp pipe. The cat suit will allow a character to have jump attacks and climb walls and goal posts. The transparent warp pipes will allow a player to "see what he's up to."
Players using the GamePad will be able to use the touchscreen to freeze and grab enemies, stop moving platforms, and find invisible coins and blocks. Players will also be able to control the camera with the GamePad’s Gyro Sensor, making it easier to find hidden objects.
For a second there, I thought "New Super Mario 3D World" was the title...Thanks for the heads-up.
