I played this a ton this weekend and I'm loving it. Funny how this technical alpha is an order of magnitude more stable than the SFV beta. I get into a decent ping game usually in under 30 seconds and sometimes it's near instantaneous.
I'm pretty much only playing Crow right now.
The biggest issue right now is none of my 4 fightsticks work with this game. When I use joy2key it still doesnt work because the game attempts to access the joystick then ignores all signals which kind of block out joy2key as best as I can tell. I'm playing on a xbox360 gamepad and it's pretty brutal. Fighting games with an analog stick are not ideal, I have a lot of trouble double tapping to dash. Because of that I'm pretty much only kinetic jumping because it only requires you to be holding up during a k-cancellable move.
But hey, it's an alpha and it actually works so I'm not gonna complain too much
