Getting the badges is impossible due to the lags. One missed Note or even just a lag ina 'hold-period' takes points and you lost an perfect award... that's very sad, since it's such a cool game :-(
Suns are DEFINITELY attracting the ball more than planets, there's no doubt about that. They even attract balls already having stopped on the surface of a different planet whith much more mass than the sun. it destroys the whole game, since you cannot really estimate the way of the ball in the last rounds. 2 Points
