While the demo is the mostly what was shown at Tokyo Game Show it is more polished. One notable change is if you miss a quick time event Ninja Blade just doesn't pop up with a black screen that says miss. Now the game fades to gray then says miss and time automatically rewinds before the quick time event happens. Little changes like this make Ninja Blade gel better, but it doesn't seem like you're penalized at for missing most of the QTEs. Since this is a demo this could be just a demo thing or it could be a final game thing. Not sure, but Ninja Blade would have been a better experience if From Software had alternate fates for Ken if you missed a QTE similar to Dragon's Lair.
