Sparks, dust trails, ball trails, smoke, fire, water, slime

Hi everyone!

I have added some particle effects to make the game look more exciting:

• When robot arms move up/down and rackets move left/right, a few sparks spread out in all directions.

• When robots move around the court, they leave a trail of dust behind them, slowly rising and disappearing shortly after.

• The simple trail behind the flying tennis ball is now replaced by bright, moving particles.

• When the ball is hit by a robot racket, there is a little explosion effect emitting some smoke out of the moving racket.

• The corners of the court are now featuring thick pillars, which are spitting either fire, water or slime, depending on the type of the court.

(Bonus feature: The pillars also contain spot lights which create more realistic shadows on the net and robots.)
