I love how the power items form a "K" in the beginning :3
Is the first Orin encounter just about rotating counter-clockwise like that ? What if she starts off by moving to the left ?
Which direction she first moves in wouldn't be an issue, because (like most "random" boss movement), you can manipulate which side she'll move to by being on that side of her. Regardless, Orin's position isn't important anyway. You can still do the same circular trick from the left and right sides of the screen (though it's a bit weirder because bullets will tend to come from a more horizontal angle), so positioning doesn't matter. This is the trick that I've trusted in ever since I've discovered it, and it only fails me in my derpiest of moments (you know, the kind of moments where you're playing so badly that you would die to Icicle Fall).
It's one of those strategies that goes to show you: if you
really don't know what you're doing, and you have stage practice unlocked, try something random. It may stick. I had no idea what I was doing with this attack, then I just went "wheeeeeeeeee I'm spinning I'm spinning I'm spinning... wait, I'm alive?" and realized that it was a viable strategy.
Also, the Power K at the beginning was totally
intentional.
