Minecraft
"Minecraft 4k" is a simplified version of "Minecraft" similar to the classic version that was developed for the Java 4K game programming contest "in way less than 4 kilobytes". The map itself is finite—composed of 64×64×64 blocks—and the same world is generated every time. Players are restricted to placing or destroying blocks, which consist of grass, dirt, stone, wood, leaves, and brick.
