Try to get out of here. Moving through several worlds at one time, but only seeing them in separate windows. You can get a compilation of them when you press the C, but that means you can't move at the same time. Go to the door for the next level. It takes more than just clicking really fast, show us what you got.
Use the arrow or ASDW keys to move, C to combine all the worlds in one view and the space bar to open doors.
