Xors3D: Dead or alive?

The silence. It's overwhelming.

True words. And we're sorry for that, but there is a reason. It's not that we want to stop development or abandon the game. It's because the developer of the 3D engine Xors3D that we use on G.R.E.Y. has vanished and did not reply to any post/pm/mail in the last 80 days or so. We do not know what happened to him, nor do we know what will happen to the engine. The problem is, we haven't bought a license for Xors3D yet, as we wanted to use the Trial version as long as it allowed us to. And we won't be able to buy a license now, now that the Developer is gone.
Therefore we decided to pause development on G.R.E.Y. to see how things come out. We could restart the project on another engine of course, but that is a LOT of work. We also don't want to continue development on a dead engine with bugs (And it has bugs, we thought they'd be fixed until release).
Believe me, I'm pretty upset about this. We put a lot of work in this project already, and it's not easy to just pause it, even though it all went good so far. But developing without knowing how it'll end is no fun either.

By the way here's a thread in the Xors forum, about the sudden disappearance of .Squid, the developer. We're not the only ones that are concerned:
