Ludum Dare is a 48 and 72 hour game making competition globally hosted over the internet; Ludum Dare 34 ran from December 11th to December 14th, 2015, with two combined themes, "Two Button Controls" and "Growing".
A turn-based game mechanic is the opposite of a real-time game mechanic. In a Turn-By-Turn mechanic (synonym), each player has to wait for the other to have played, so that they can play, and so on. This way, each player has the time to think about their strategy. TBT games rely less on action than real-time games.
