The game requires you to use three characters to make your way through the cave. Characters can only hold one item each, but they can still perform actions while holding an item, such as pulling a lever or pushing a box. To switch between characters, use the D-Pad. Be aware of where each character is on the D-Pad, because some puzzles will require you to switch quickly.
Each character has their own special ability, and while some are very useful others are not. You can complete every section of the game with any set of characters, but certain ones let you bypass whole sections. The following is a quick overview of the characters and their abilities.
|The Kinght||Invincibility||Allows you to get through areas where you have to walk around a long way by ignoring fall damage.|
|The Hillbilly||Hold Breath||Allows you to go through long water sections, really only useful in his section.|
|The Time Traveller||Phase Shift||Allows you to bypass a lot of doors, really useful.|
|The Scientist||Hacking||Allows you to bypass puzzles that require you to open doors by simply hacking them open.|
|The Adventurer||Grappling||Allows you to bypass small sections by grappling, but not overly useful.|
|The Twins||Ghost||Allows you to skip sections that normally require 2+ people.|
|The Monk||Telekinesis||Allows you to bypass the whole Zoo level by sucking the Hot Dog out of the machine, as well as other cases.|
