I got to play in the beta. It's a fun game. Combat is very enjoyable. Controls take some getting used to but muscle memory eventually takes over. I think this game would be incredibly fun with a few semi-dedicated friends to play with. 1v1 and 2v2 with friends would be a lot of fun I think.
My only concern would be repetitiveness. I'm sure there's more features that will be in by release. That said, I'll still likely buy it. It's a good game for being able to jump on and play a quick match or two. It's also a good game for a binge session, though as I said I think the latter would be much more fun with even just one other friend playing with/against you.
I got nothin' clever to say.
