This is the source code! It can NOT be used to play PDAFT!
If you just wanted to play the game, you downloaded the wrong thing.

For information on getting and installing the latest release,
please read the wiki at https://notabug.org/nastys/PD-Loader/wiki

You should also read the wiki if you have any issues, before asking questions.
