Bored To Death is an arcade style brawler intended as a throw back to arcade games of the past. The game's main characters, style and gameplay are based on Jason Steele's popular Marshmallow People online video series.
Impact provides some basic game collision detection and response for entities. This is often sufficient for Jump'n'Run or RPG games, but sometimes you need some more accurate and realistic physics. This is where Box2D comes in.
