Maple Story mesos scrolling viewpoint more closely resembles a platform game rather than the typical 3D environment or top-down perspective of other games, such as Guild Wars or Mud Online. The controls for the game are executed using the keyboard and mouse. The keyboard is used for many game functions, and much of it can be rearranged to suit user needs. The mouse is mainly used to trigger non-player characters and manipulate items. Players are allowed to create multiple characters in each world. Each world, similar in content between each other in the same version, is split into at most twenty channels, among which characters are allowed to freely switch.
