Thanks for playing and recording!
The music bug has been fixed as of the newest update. Dialogue getting stuck might be due to where you're clicking, but I'll have to check that again. Try clicking on the text box area at the bottom and see if that fixes it.
I recorded a run of my own for you to see. I've skimmed through bits of your video, and the core issue is that you're just not playing aggressively enough.- Forgot to mention, but 1-4 or D-Pad will change abilities. The mist teleport from mid-air and it's follow up attack has some of the highest damage values, which is why I use it after performing the finisher.
- When she's going from armoured -> unarmoured state, that's your chance to hit her. Interrupt the transformation enough times, and she'll stance-break herself.
- Dodge/Sprint -> Kick is another very useful move. Actually, all of the kicks are very useful.
- Attacking/Kicking after deflecting will do a faster counter attack. Generally, most of Louise's attacks can be counter-attacked safely.
- Against her Excalibur move, all you really need to do is dodge to the side when she turns to face you. Or you can jump over her, or you can mist form through her, or simply walk to the side, and even possible to parry it if you dare to.
