Super Mario in Javascript – Size 14kB

It is awesome!! Try it.

Regular version: no music or with music

Double size: no music or with music

Press return key if you are not able to hear sound.

Here’s an experiment in keeping things small and confined to one Javascript file. There are no external image files or anything, everything is rendered with Javascript using either canvas elements or old fashioned div-making tactics (for IE). The sprites are stored in custom encoded strings in a format that only allows 4 colors for each sprite but in turn only takes up around 40-60 bytes per sprite.

We also have MIDI music embedded as base64-encoded data: URI’s. No music for IE, though, and it seems all the other browsers each have different, minor problems with it, but it sort of works.
