Construo

Construo is a construction game written by Ingo Ruhnke and licensed under the GPL. The latest version of the game is 0.2.3 released on April 10th, 2013.

Gameplay
The game provides particles that can be connected by springs (beams) of arbitrary length. Also rectangular colliders can be placed to deflect moving Particles. After pressing "Run" all (not fixed) particles move and forces inside springs are indicated by red colouring. If stress is too hight, springs will collapse. Scenes can be saved and loaded as a "*.construo" text file.

The game has no specific goal and is "neither a real simulation nor a real game" (I. Ruhnke), nevertheless following game ideas are suggested:
 * Remove a spring: turn based removing of a spring without collapsing the tower. As a multi player game, played in a round, player that crashes the tower is out. Multiple rounds will be played, several stable objects must be provided.
 * Hot-fixing: the player has to stabilize a falling structure in slow-motion mode, if he fixes it he wins, else he loses.
 * Task-force: player has to complete some task, like build a bridge or something else with limited resources.
 * Demo mode: let a bunch of machines do things automatically.
