One problem with all JJP games is not knowing what to shoot for and why. They generally use all the lights all the time making it hard to figure out what needs shot. During the song modes, the lights are following the song, which leads to some awesome effects but also to further confusion as to what needs shot. The large display is full of information, but, with so much on it, it's hard to know where to look for what you need while playing. You almost need a "spotter" for a few plays.
I find it to be a fun machine, but with some of the typical JJP weaknesses (the lights not being telling enough, too much multiball, sluggish flippers). To me, it's JJP's best game to date, followed by PoTC.
