"Clonk is a computer game developed by RedWolf Design. The game features a mix of the action, economic simulation and platform game genres. The games of the series are traditionally released as Shareware; older versions have become available as Freeware. Using the integrated developer mode, experienced players are able to create extensions on their own.
In Clonk, the player controls small, humanoid beings - the so-called Clonks - within a two-dimensional, dynamically modifiable landscape using keyboard or mouse. Clonks interact with their surrounding landscape, animals, buildings and objects. The game can be played alone or in multiplayer in split-screen or via local network or Internet. The game goal depends on the scenario being played, varying between melees, in which players fight each others, strategical team siege scenarios and cooperative missions." Cited from Wikipedia.
