Gameplay
The game features string puppets that allow for complete control over their hands, arms, and the like. The game is written in C++ and Direct3D though it is only played in two (and a half) dimensions and exclusively with the mouse. RDKF uses multiple mice to implement multiplayer on a single machine, but this feature is limited to Windows XP due to the use of this Raw input code to implement this idea. An online multiplayer feature has been added to the game as well.
