Motivation

Roody:2d has infinite procedural generation, so the world is split up into 64x64 tile chunks.

Before version 0.7.0 alpha, the data for each chunk was saved into a .sac file. Each tile was 4 bytes, so the files were each 16 KB (4 * 64 * 64 + some metadata).

This was very simple to implement, but had 2 problems:

Recreating Qbeh-1

Placing and removing the puzzle cubes in Qbeh-1 works differently in Minecraft.

In Qbeh-1, you can pick up a cube and it will instantly go into your inventory. It has the restriction that cubes must have some connection to a yellow block, when placing or picking up.
