Characters are what the player uses to interact with levels. As of version 126.96.36.199, there are four player characters available to choose from, each with their own abilities and optional settings accessed through the in-editor level menu. The playable character in each level is set by the creator, however, picking up Character Capsules can allow the player to switch character.
All characters are capable of moving left and right, as well as jumping, shooting, and climbing ladders. In addition, all characters are capable of using a primary weapon with infinite ammo, as well as up to 11 extra weapons which have limited ammo. All characters have a total of 28 health, along with 28 ammo per limited weapon, which can be restored through the use of pickups and weapons. Each character has a unique default weapon, as well as at least one unique utility weapon.
