Derek will probably open-source the game (definitely will?) (says he's planning to move on to other projects)
In the meantime though, the fully-commented source code is available:
1. use GM Decompiler to extract the .gmk file from the .exe
2. the .gmk is encrypted, but you can use the trial version of Game Maker to view the contents of the .gmk, or use LateralGM to view it
3. If you're interested in only the scripts, you can use Game Maker to output them to a text file:
  - Scripts > Export All saves all non-object code to a .gml (text) file
  - Edit > Show Object Information > Save Button saves all object code to an RTF or text file
