Right now, you can go to http://www.byond.com/games/IainPeregrine/plundergnome and click on a neat little [Zip] link to grab the .zip file for the game. Awesome! You can also go to http://www.byond.com/games/IainPeregrine/ plundergnome&format=text and get a bunch of plaintext information about the hub.
It'd be great if the format=text provided a straightforward link to the zip. Preferrably without any ?user=whoever&hash=whatever, just a straight link to the zip.
