Nice. So basically Super Puzzle Fighter II Turbo just without the Street Fighter II stuff..?
1). I don't recall ever hearing any pops in the music, testing on ~4-5 different Symbian phones of the time. But I never tested on QD specifically as I never owned one.
3). I don't recall enough about the controls as I haven't played in years, but we found them serviceable enough to play through to the end.
