LWJGL16K is a competition for Java developers writing games with the Lightweight Java Gaming Library. The challenge here is to squeeze a game out of a mere 16KiB. Judges aren’t decided yet, nor prizes, nor a solid deadline in fact – though there are likely to be at least some of those things soon enough. Everyone participating will get their game (or games, submit as many as you like!) showcased here on LWJGL16K.
Keep an eye on the official contest details page for the currently announced rules, judges and such.
