6-6 and 9-4 down. Also went and glitched Hatate's spoiler scenes with Aya (did I do that before?) just to be able to say
97 scenes in DS cleared without using focus or switching the camera alignment with Aya!These scenes are both pure puzzle scenes, I'm looking at 6-6 in a new light now, it feels like it was a wasted pattern when you play it for a normal clear, since you don't even need to dodge anything. It got relatively easy once I got the hang of when to dash through the openings in the crossing bullets. For 9-4 I just learned a way to position Koishi that made the helix keep moving in the same way all the time. It's quite humbling when you suddenly realize something new about a pattern which was there all along but you never noticed it, makes you wonder how many players actually saw it before their first clear. Much like how holding shift increases your camera's reach, something I never noticed before I started playing no vertical. Anyway, I'd say that the most difficult scene so far was 10-1, it just wasn't made for this challenge! But it was considerate of ZUN to make it survivable even without the camera.
Excuses Summary of the remaining 11 scenes:
4-4 This would be easier to do no vertical than no focus.
6-7 Get lucky 5 times in a row to win!
7-4 This might be the only one which is actually impossible, unless you can dash through the lasers like in her midboss spell, but I sort of doubt it because the lasers seem to be slower and thicker.
7-5 Not impossible, only inhumanly difficult.
9-1 First phase is pretty manageable but having to navigate the second phase is way too hard for me. I can see it happening, but even then there's the last phase and I'm pretty sure the short range will hurt like hell there.
9-7 Just luck for me, really, I don't think I even got to take the second photo even once.
11-4 while this is actually rather interesting like this, because you actually have to dodge and not just sit on Suwako and cancel bullets, it seems like the bullets move in certain ways depending on your position.
12-4 Easy enough with just no focus condition, but without the extra range the knives seems to pile up without end. Still, probably one of the easiest remaining scenes.
12-5 You have to squeeze through a gap a few pixels wide and the playing area is a shining mass of additive blended glory.
12-7 Too hard for me. There's just too much stuff and I suck at dodging these to begin with.
12-8 Not too bad until the spawning speed picks up. Micrododging this without focus is icky.
Maybe it's time to pick up scoring again now; I'm sure that many new wonderful realizations to come from that

Also congrats to you crazy superplayers and your full game runs. You are too damn good!
