I'm not too keen on the smoke, but the rest is looking mighty nice, cairnswm!

Huehnerschaender, yours are looking awesome too. I especially like the screenshot with the tank.

About demos. I'm not sure if I'll release a demo immediately after the deadline of the current stage, but there are definitely going to be releases a bit further down the road. I only have 3 pc to test it on, mayby four. But by releasing it, I may get more input from other users.
