#JALE update: I've been working on some new graphics. This includes different graphics for different orientations; you can see why this is important below (Left is different graphics for each, right is a single graphic rotated)
However, the editor can't handle more than one graphic per tile, so I have to write a system that turns a block ID and a rotation into the proper graphic. After this is done, the matter of saves will be trivial, and I'll release 0.0.2 with the following features:
New graphics!
More colors of metal blocks!
The ability to put gravity effects in a separate layer!
The ability to save and load worlds!
