I know it looks like a bug at first and maybe we should have stated in the game that the ball was going to be visible for the entire level. Here's why we did it: When we first started Pathstorm, we planned on making the ball invisible all the time except on levels where we threw in an unreasonable number of objects
. On those levels, we made the ball visible to compensate for the increased difficulty. Just imagine how difficult that level would have been for a beginner playing with invisible balls!
