For those who don't know, Minecraft 4K was a stripped down version of Minecraft submitted by Notch to the Java 4K Game Programming Contest, where each submission had to be under 4 kilobytes in size. Its wiki page can be found here.

Being so small, the game proved somewhat easy to de-compile and edit. Multiple people have given this a go, including me.

This project is an attempt to translate the game into C in order to increase its performance, and to provide a platform upon which to add new features.

Bug list

"Sticky" block collision - this behavior is present in the original version and I have been trying to work out ways to fix it for a while.
Block outline cuts off at mouse x position.

Goals for this project

Maintaining the original look and feel as closely as possible.
Keeping the final executable under 10 KB (on Linux, with the system I have set up in the makefile)
More blocks
Perlin noise terrain generation (water, caves, etc)
Infinite worlds, possibly vertically too
Mobs and multiplayer (this would require changing the rendering engine to some degree)
Day/night??? I don't know whether or not this would change the look or feel too much.

Dependencies

Bare minimum to make this code run

SDL2
A C compiler

To get it down to a small size, you need

gcc (have not tried the flags with other compilers)
gzexe
