Game is great, but closing it is a bitch!
... Ltris doesn't seem to work right with my ximian desktop, clicking the 'X' in the corner of the window doesn't shut it down.
'esc' requires a 'y' to confirm shutdown, at which point that's one step to 'game over', then another to the 'new game' screen, another to the main screen, and finally one more (plus waiting for fadeout) to quit. That's five keystrokes to stop playing.
Also, it takes over /dev/dsp even when audio is set to 'off'.
