Hmmm
To be honest this game didn't really fetch my interest..
First of all, I though the graphics were too sloppy, could use some sparkly stuff. :)
Second, Why would you make a time bonus, if there is no time limit/time counter?.. You can't see how much time you have used, but you still give bonus for completing the level fast.
Basicly the game is only about mouse control, which makes it too easy. If you had to control the sphere with the keyboard, it would have been more interesting.. And perhaps giving you special features when you upgrade the sphere into another colour.. Dunno..
It was just too much of the same.
