I think the base controls feel terrible. r1 as the dash just feels shitty, the dash feels better if you throw it on l1. This is my control config.:
Also the tutorial doesn't tell you how to do the backjump thing, it helps out on boss fights and lets you do cool stuff ("backjumping" in the direction you're running feels cool)
Ray was a pretty fun boss and way better than the intro tank, but her gameplay is really unbalanced and you can just cheese through stages and bosses by exploiting her cancels. (I bet ray being a girl is because people always thought zero looked like a girl when they first saw him)
