Whoa, i played this on a beamer, with dolby 5.1, now i got psychosis... Anyway, this is how you get 1000 on hard: play on fullscreen (F1), be relaxed (talk to a friend while playing for example), gently circle the mouse around the center, and do not drink alcohol! ;-)
After a total of ~5 hours of playing, this is my rating: O.M.F.G.
I'm completely blown away by this game! Also my friends who aren't very familar with computer gaming are truly amazed. BUT what I don't like are the blue chambers, which often are unpassable, especially at 1300 - 1500 km/h on easy (which is my favourite difficultiy), it's kind of a motivation killer. But I finally got it to 1492 km/h on easy :-) My pro tip: dont't panic! Ceep cool! You have to stroke your mouse :) Try to swing around the center of the screen while gently moving your mouse. Also alcohol does help ;-)
