MC [Beta 1]
The ball has almost no bounce to it, and is near impossible to get off the ground.
Jump [Beta 1]
The ball if right in front of you being pushed slows you down considerably.

I think the ball needs a lot less weight to it, if that's possible. As jump said, it slows down the car (I don't know if this is just because it's touching the tires though), also, it's very hard to get the ball off the ground. At first I thought it was impossible to do a rocket chip, but I pulled a very small one off finally. The ball popped up barely enough to go over a car, but I now know it's possible. Right now the ball feels like a dead weight, slowing the car down, pushing the car back, and barely ever getting off the ground enough to bounce.
