Smoother in what way. It's already smooth. If it was any smoother at all, it would look like the ball was moving on ice.
> Is the wall jump supposed to be there?
It's not possible that one codes wall jump without knowing it.
> Make this multiplayer :O
No, this was asked before. I am not planning to do that, because the delay with pressing keys in multiplayer is horrible.
