Skewed common sense -- dynamic court

Hmm.. think about this, to make the game more fun, we can have a moving court instead of a stagnant one.

Type 1 -- simple random moving
The court will move along one axis, namely the goalposts-directions. The movement of the court is random. So if you're lucky, the goalpost is moving toward you when you are attacking.

Type 2 -- complex random moving
The court will move randomly in all directions in the xy-plane. So in addition to your goal moving futher or closer, your ball will risk floating out of court too. When shielding, you will take a little more effort to push your opponent out to gain possession of the ball.

Type 3 -- random expansion/contraction
The court will expand or contract randomly, along the width of the court (not much point expanding the length). It differs from the above two as when it expands/contract, its goal enlarges/shrinks with it. Hell of a job for the goal-keeper.
