That's funny.. I haven't seen anthing like that cloud when playing. You jumped really high.. Now that I actually found this thread.. are there anyone from Rovio reading this? I know there's at least one member here working there. The issue I have with the game is that it'll only play if you hold the N900 horisontally, which I never do. It's more like 45, or even 60 degrees vertical. To hold it horisontally would be really awkward. What about an update which calibrates the 'zero' position when the game starts, i.e. just like the 'sheep' application does? (The above doesn't apply to the racing game of course, which only seems to care about the side-to-side accellerometers)
