That game looks really great. I've played so many roguelikes and was instantly interested. Reading a good post mortem was another plus to check it out.
Then I remembered the general problem with commercial games.. went straight to the FAQ and searched for "linux".. bummer.. I guess somehow I expected a roguelike to work on Linux :)
I will observe the game and hopefully someday a Linux version will emerge. Good luck to your quest as indie dev!
