Regarding the volume of the new special effects, I do have the impression that the volume is rather low, even at a setting of 200.
Compared to the standard music volume (100), I think a sound effect should be audible above this volume.
So, to be audible, the volume should be adjusted (setting higher than 200). Or the volume of the special sound effect should be at least as loud as the standard music volume (100), with the option of increasing it to 200, as is currently possible with the music.
