I've uploaded the first public release of Provenance. Download it in the Downloads section. Be sure to click that 'read more' link to see the awesome people who've helped me complete this -- they definitely deserve it.
I've also uploaded the map sources for any developers who are interested in seeing how some things are done without having to use a decompiled mess. You can check that out here:
And check out my website for information on my first Left 4 Dead level, too! It's set in a mall!
Edit: I didn't really wanna mention it but this was made as a portfolio piece -- a quick run-through of various settings, a puzzle or two, a battle arena experience, and some cool ramp-up to an end. Don't take your black screens and lousy computer crashes too seriously. And yeah, the black screen at the end should have discontinued the game but game_end is broken. Whoops.
