Options for plane, rocket or car required levels

If you choose to play on plane required levels, you get certain parts you would see on a plane (such as wing shaped blocks, rutters for turning, ect.) If you choose to play a rocket required levels, you would get rocket boosters (enlarged rockets to save time while editing) And if you choose to play a car required map, well it's the same as the normal levels and parts. Overall each category, you should be able to place extra characters like passengers.
