Pointless updates

As you may learn by looking at it, this game is pointless. It has a few basic rules:
-It has no players.

-Cannons start at a random position

-When a bullet touch the opposite colour goal, the team score a point and moves pushes the scale bar to their side.

-Bullets destroy themselves when they touch a bullet of the opposite colour.

-"Sentries" (or the pointy things that goes from one side from another) get destroyed and respawned after some hits.

-When the scale bar reaches the other side of the screen, the game ends, records the score, and restarts for further pointless activities.

To add further pointless fetures:

-There is a random car that goes side by side sometimes, it pushes bullets away... it serves no purpose, one may think that it could change some results, but it doesnt.
