It always starts innocently enough; The level opens, you begin walking forward, maybe jump on a platform or two. Then IT appears. IT chases you, dogs you, tries to trap you, squash you. If you aren’t fast enough… IT will kill you.
I am of course talking about Scrolling Levels. Or to be more specific, forced Scrolling Levels where the “camera” or borders of the screen will move in a certain direction across the stage and if you don’t keep up you will either be shoved into a bottomless pit or crushed between a border and a hard place. These types of levels are most prevalent in 2D games, but sometimes they can make an appearance in 3D ones as well. In scrolling or on-rails shooters, a scrolling camera/level makes sense since the entire game is designed to push you forward without any player input. Platformer & action games on the other hand, you are in full control of your character’s horizontal and vertical movement so having the screen push you forward is an unnecessary complication.
