I've beaten the Underworld level twice now, but I haven't gotten the achievement either time. I was having trouble with my wifi earlier, so I was playing the first time in offline mode, but I've since resolved that issue, and beat the Underworld again in online mode. Still no achievement. I've rebooted my computer, but still, nothing's syncing up. Any help is greatly appreciated. Thank you....

What should I do in the main menu? I mean, there are some buttons, but none of 'em seems to work. Dunno what to do, any suggest?

Will there be a native GNU/Linux build of the game eventually? That would be awesome.

add some pls???
