<- the guy who made the engine
because it takes some work to do the "release", there isn't a "release everything" button, we have to track down every single asset made in these 3 years, package them appropriately, and upload them in a good web space.
I for one would have to do some work on the engine in order to get it working again for release, and i can't guarantee it will work perfectly on all supported platforms (i have only linux).
So, we just thought it would be good to see if there was ANY interest on it before doing all that work.
and on a final note, the game had been over 2 years looking nothing like x-treme, the engine is completely different
