An update on Imperishable Shooting:
Reimu Solo seems to be the best choice for this, since she has the smallest hitbox. I'd go with Border Team, but Yukari can mess things up when Time orbs make it harder to see.
As far as I can tell, only the first wave is static, and the space between bullets is just enough for Border to slide through the gap. A single tap to the right followed by grabbing the bottom is enough to dodge right through as the ring expands.
The rings also burst in a spiral, rather than straight out - gives more space, but harder to predict effectively.
Waves three and four open in the same manner every time, but the burst points are always different.
Oh, and the points I noted earlier (that the overlap bullet is the burst point) is false. It's usually the bullet next to it that goes out all the way.
The bullets seem to accelerate as they reach the furthest point, so clipdeaths are common.
The second wave of five requires movement in the opposite direction from the first wave of five.
That's the furthest I've gotten so far, in <100 tries.
Also, damn you Hourai Elixer -Hard-.
Also, reply number 666 (pasonia got post 666)!
