I think there is some more work to do:
1.) The player-ship sometimes "escapes" the screen upon start-up.
That's because the ship always tries to reach the mouse-position, and if the mouse never has entered the applet, this goes wrong.
I'll define a starting-point for the target-position, if the mouse has never entered the applet.
2.) The hitpoints-bar of sunk ships should disappear. It doesn't look good...
3.) The reload-time of the cannons should be visualized. Maybe there should be 2 separate times for the left and right cannon...
4.) The enemy-ships sometimes appear to close to the player upon a new stage. I'll move the randomized spawnpoints slightly outside the screen, so they sail in (and don't pop up suddenly)
5.) The cannonballs should make a splash in the water, if they missed...#
6.) the pirate-ships should try to avoid each other. Looks odd, when they pass through another ship...
7.) Stuff all that into the remaining 19 bytes...

Well, I'll have to clean up the rendering of the ships a bit, to make space...

Any more feedback? Anyone? Please?
