It uses a custom form of compression, so the save data is packed into binary, which both makes the savefiles smaller and also makes it impossible to understand just by looking at it in a text editor or hex editor.
Of course, it could be reversed by someone decompiling the game, analyzing the code and undoing the compression, but the same is true of any savefile "encryption". If the game is capable of decrypting a save, then it is always possible to reverse engineer the game to get the algorithm and decrypt the saves manually, but that is much more difficult then just editing numbers in notepad. Also, the fact that this is a native code dll makes it somewhat more difficult than usual for GameMaker games, which are trivial to decompile.
P.S. I haven't been here in years, but today I decided to check up on the forums again, just out of curiosity. It's a good thing I saw this.
