Hiya, enemy missiles seem to come down at the same speed through levels 5,6,7 but seem to speed up quite a few bonus rounds after level 7, usually when im somewhere between 2,500 & 3,000 also it seems the missile kills you almost straight away instead of lthe frame where it disappears of the screen. I know the site was down all day not long ago so i wander if thats got anything to do with it. Cheers :)
