You know there's a copy video url at current time button, right? You don't have to tell us where to go. Why is your health so small? Riku isn't hard you just need to gain more levels.
I wish the Riku fights were long like that for me. Spam Sonic Blade and that guy is going down without a fight. Seriously, he can't take a hit from that move worth crap. In fact, the same happened with Larxene, only Axel, Marluxia, and Vexen could make a difficult fight.
The auto-embed doesn't support starting at a certain timestamp, you'd have to link it for it to work.
