I've tried the Linux demo, and aside from some black images in the tutorial I'm not sure were supposed to be there everything seemed to be running fine!
Yep ditto. Only the last tutorial image showed; the others were black squares. Game seemed to do well otherwise!
(edit: also mousewheel rotation only works in one direction... not sure if that is intended)
same for me. I did notice intermittent flashing on the end game screen.
Wasn't sure if that was intentional nag effect to say go buy it?
Also, same as Joel B with the mouse scroll.
