I've played this back when I was in gradeschool, now I'm in college, I hold fond memories playing this game. Having to play it with my younger cousin in where I use the keyboard and he uses the mouse xD Even though flash doesn't have any support anymore, I suppose it will always occupy a special place in our childhood :)
