The IdeaHack competition is a game programming competition with a difference - namely, it is defined by its entrants. Each participant submits one 'requirement' before the competition. The requirements may govern gameplay and game design, but not technical issues, and genre must remain free.

Due to the fact that some entrants could not create a
playable game with the given time we decide that the time period
will be extended by exaclty a week
( so it'll end Friday 28 September 24:00 GMT ).
