Js13kGames is a JavaScript coding competition for HTML5 game developers. The fun part of the compo is the file size limit set to 13 kilobytes. Theme for 2014 is The Elements: Earth, Water, Air and Fire. The competition started at 13:00 CEST, 13th August 2014 and will end at 13:00 CEST, 13th September 2014. See the Rules for details, good luck and have fun!

An ASCII-based Roguelike could work really well for this. Kiwi.JS has a started package (a "Blueprint") for one here.

I don't understand how last years winners got these games to fit in a minimized and zipped package at just 13kb:

Looks like Jack Rugile is the guy to beat, he won first place prize each year. I just realized there is a first place winner in three categories: Desktop, Mobile, and Server (node.js).

How to Minify Your HTML5 Game for the Js13kGames Competition

They are probably procedurally drawing most the graphics, which would explain why they are more colored shapes than images. Images and sounds will bloat the file size more than anything else, so they have to be avoided as much as possible. You could get a lot more out of each sound with the Web Audio API, and draw a lot of your graphics.

code wise 13K is not small... but for the remaining content indeed it can be really a limitation. I would participate, however I simply doubt I have the time for it.

Yeah, once you add in minification and gzipping, 13kb can be a ton of code. More than enough to do a lot of drawing and use Web Audio API.
