Level in pure form (the format the game save files use):

Seperated by spaces.

First segment is width number

Then repeat until you get an empty segment:

Read length

Read tile id, (run length encoding)

If there is no segments, you’re running with the legacy level format, you’re done, use a flat wall.

Now read rotations, also run length encoding.

Now read data, just read until blank segment, will discuss how to read data later.

Now read the walls, until there's a blank segment, read wall height and type

Now read the hue, if the hue is not empty, read hue 2

Data consists of a list of tile index, then data string

How to convert level codes to pure form:

Remove magic by chopping off first 7 characters (or is it 8, or 6, i forgor)

Replace Z with space

Replace plus with B

Replace minus with C
