I just tried Ragna Mau, that was really fun.
He doesn't exactly play like Ragna, but I had fun with his movelist. He has a couple of problems here and there (some of the basic A=>B=>C combos don't actually *feel* like they work or are effective at all).
He needs more hitpause in his basics, they don't really feel like they're hitting. One other problem I found is that combos that work mid-screen sometimes won't work in the corner because he's pushed different distances, you might want to check that.
Let's go, one final stretch!
