Is this Saito's debut game as a director? If so it's probably the best debut game for a young Japanese director I recall from recent history.
Got the Stormbringer trophy, letting the adrenalin wash off while I listen to the credits song now. Hilariously enough the final boss's worst phase was the second one, since the cartwheel is so unreliable, even with the "option select" strategy of running to opposite corners. I S-ed the third form on the fourth try, but it took me a couple hours to get past the second phase. I even did the cutting sections for kicks to make it go faster, it's much more lenient than sundowner's shield cutting.
Yes, he was lead programmer on Bayonetta. Yeah, the dodge and wait section of Armstrong is the worst part. For the cutting part on Easy, the boxes are HUGE. It was so funny when I got to that.
