It's fun and really does have a different feel from Smash, but Smash is better. Not a bad first entry but it needs a lot of work.
It also can really stink when you're playing a match without a time limit and it gets down to two people, who then can't kill each other since it starts to take forever to build up meter and it gets easy to dodge each others' moves. I had to quit out of one of these matches as a spectator (five+ minutes of this was enough) and it felt like hours passed when I was the surviving player in another. Doesn't happen in ranked though.
