Put together some quick notes on how to do this, uses demo version from defendersquest.com & assets from the GOG Mac installer file.

May be some use to some ppl here.

That is certainly some clever hacking. I'm impressed!

Although you seem to be aware of it and prefer this solution, for those who don't know, I actually have a fully native Linux build available directly from my site. The only reason it's not on GOG is because GOG currently only supports Mac/Linux.

I'm sure if you guys bug them about it enough they might start hosting our Linux build :)

Thanks, love your game.

re: gog hosting the linux build, I'm sure they would host it if they could. But they can't because then they would have to give support for a 3rd OS. They're not quite ready to do that from what they've said. But hopefully in the future.
