$9.99 Value! From the Steam Store:
Paperbound is a smash-up brawler that combines platforming, twitchy combat, and gravity redirection in a competitive couch multiplayer setting. Between one and four players run with scissors, walk on walls, and lob ink bombs in whimsical-yet-intense battles within the pages of old books. In addition to the 360 degrees of gravitational freedom, several other twists add to the tension and drama of a match, such as the "escape through the page tear" victory mechanic which brings a second phase to the combat and causes players to momentarily team up with their adversaries.
Play as one of Paperbound's 11 original characters or as characters from Guacamelee, Monaco, VVVVVV, Cards and Castles, and Tumblestone.
When your friends aren't around, Paperbound features challenging AI bots. Each character has his or her own personality. Some are aggressive, some are more cautious. Some are even vindictive. Some make adept use of all weapons, while others prefer to get in close for melee combat. The bots are great for solo players, for when you want to even out the teams, or for when you simply want some extra chaos.
Battle within the pages of old classics.
Compete in team or solo battles in a variety of game modes that will keep you laughing and screaming for hours.
Note: Paperbound does NOT support online multiplayer. It supports local multiplayer by connecting multiple controllers to your PC, so invite your friends over, plug in some controller, and have a great time. Currently, only Xbox 360/One controllers are officially supported. PlayStation 4 controllers have been confirmed to work using DS4 Tool. Other controllers may work using XInput wrappers, but compatibility is not guaranteed.
