Thanx for the comments and hurray for physics

Well I am plannign to put some nice sun's and planets (maybe rotating around them) in the field, but the game will be not to defend something or much action, it'll be a puzzle game. You have to find the right angle and speed to navigate your ball through the level and pick up as much items as you can on the way to the target. That will be the game in big lines, and I'll try to add some nice effects and more nice functions to it.

But I'm stuck on the damn GUI now I hate 3dgs on that part.
