Thanks for the heads up!
Have you tried the latest version, from here?
If it doesn't work, can you name (not link) a game?
Thank you for the info! I think the new version I just uploaded can handle this too.
One fun thing about this is that the game apparently uses art under various CC licenses, which prohibit DRM. (Although theoretically it's possible the game author got additional permission from each of the authors.)
By the way, using DragonUnpacker, some (all?) files can be extracted, although it's much less elegant. Guide:
