i just found this game and installed it. i'd gotten it working in windows but when trying to install it in my ubuntu vm after install java and all that it fails. The window for it pops up flashes several times then disappears. I used http://www.ubuntuvibes.com/2011/03/spiral-knights-new-game-from-makers-o... to install it(of course changing the java part to the version i have and whatever else that it said to do). otherwise when playing on windows a great game :D
