A level in a Platform Game where the screen scrolls at a constant rate (like in rail shooters), no matter where the player runs or jumps to. This doesn't make any sense at all, but since you didn't care when you were 12, why start now? These levels can be a bit aggravating to play, particularly when combined with any number of Classic Video Game Screw Yous. It's debatable if Minecart Madness is a subtrope. It takes the concept further by forcing the player to move a fixed speed, and challenges them to jump, duck, and\or attack at the right times.
