In the current 1.0 version, the zip includes full source and a Vorple website AND a gblorb. I couldn't get the Vorple website to display images, even when I ran it on a localhost server, but the gblorb displayed images just fine, so just use that. It's in "Project New Media.materials/Release/The House of Mystery.gblorb".
The puzzles I encountered were interesting, but eventually I got stuck. The game doesn't offer a walkthrough or in-game hints. The game doesn't credit beta testers and has a lot of "You can't see any such thing" errors.
I look forward to a future version of this game.
