Quite short so I was able to try both battle systems.
Definitely echoing other s though in that the timed-battle system felt better to play (and it was easier and faster XD) Kinda wish there was an ability to dodge attacks like your other game :P (even if I didn't really need it)
on the magic system, I found the spark attacks to be a wasteful usage of MP since there was no difference in damage seemingly, and yeah it felt like it was just dragging too long with both fights since they're nothing but make enemy number go down, increase own number when needed.
Having never seen or read DBZ... All references flew over my head :P
