I know.
I used to upload stuff on that page. But that was so long ago...
And now this part may seem odd...
I played the game so long that I could imagine all the sounds in my head while I kept the speakers turned off. Both that of units and the melody.
And I also did an experiment to confirm this. My friend was a supervisor. I was playing the game with the speakers turned off for ten minutes. Then, after ten minutes I started whistling a melody and turned the speakers on. I was at the exactly same part of the same melody which was playing in the game.
Yes, I was playing games instead of studying. Don't judge me.
