Oh yea don't worry I'm planning to remedy the collision detection since right now it's checking for the ball's registration point, which is in the middle, and it can get wierd where the ball gets caught in some strange middle of the line. As for the line idea I am defenitely going to code up a little lifespan as well as restriction as to how much of a line you can create.
So yea it's all coming soon. But keep it coming I love getting feedback.
