Updated gameplay, sounds, and music!

I updated the gameplay to include a battle system although Ecco cannot take damage yet. The music and audio have also been updated. It's pretty rad now! When the psychedelic screen saver plays, it looks and sounds like Ecco is splashing into deep water! ^_^ Also, the Killer Whale has been re-named to "Shamu." Remember the orca from Sea World? Do you see the graphical error at the end of the video after Ecco defeats Bismarck? I'm going to fix that next along with the transition between phases! ^_^
