The infinite arenas thing might have seemed like a good idea, but in this game it doesn't really help at all. I know I said that I didn't think storyline adds too much to fighters, but you do at least need a strong line-up of quality characters, and again this game does not deliver. Kazuma is probably my favorite character, although even he is just your average Ninja guy. Graphically, Galaxy fight is quite a mixed bag. Gunter's stage has nice reflections in the water, and Musafar's has a nice rain effect.
All stages use LOTS of parallax scrolling too.
The one other plus point is the games introduction sequence, which as I mentioned, doesn't show any of the games plotline, but is very pretty all the same. The music and sound effects are a bit of a mixed bag too. Most of the music sounded to me like it was just made solely for the purpose of being noisy enough to attract peoples attention in a busy arcade. It succeeds in that goal, but while sitting playing it at home without any other noise to distract my attention, the music didn't do much for me at all. The only piece of music I liked a little was Kazuma's, which is kind of a mysterious techno-ish tune.
