I played the demo 10+ times, and probably repeated the boss fight about 30 times. The game never froze, but I got a bunch of other bugs:

-Raiden leaves the combat zone during one of those Blade Mode animations and I can't get back in.

-Blade Wolf stays on top of that building and doesn't come down.

-Attacks in Blade Mode are very stiff.

-In VR training, slashing the indicated point on the wooden targets doesn't always give you a 100 points, it's just ignored.

Also(not a bug), hitting the last female wooden "hostage" reveals her bikini, lol.
