Dragon Legend Z, or is this A DRAGONBALL Z FIGHTING Game With BAD Gameplay?

Dragon Legend Z is an interesting game... First of all it's called Super Saiyan Legend when you donwload it, so it already has a different name from advertised in the store, and then there's the art and gameplay. Is this a rip off of Dragon Ball? Or is this legit a DBZ game? Cause all the characters and art work is Dragon Ball. But I highly doubt it's an original game because the controls and combat is terrible. And the life pool is massive. It takes forever to take down opponents. It seems like your attacks do almost zero damage. Also the menus are hard to look at due to all the clutter. I don't recommend this game. It's pretty bad. Not a fan.
