Go take risks on stage 1, any damage there can be immediately repaired by esc > retry

But if the restart count on that stage is over ten...
go take a rest well deserved play more carefully. Summoning 2 Red UFOs before midboss Nazrin, make sure you have 2 UFO cache while fighting her, then you are free to choose summon Red/Green UFO.
Be very careful when chasing UFO before Kogasa midboss. Or better yet, pick one then wait until Kogasa arrives. Then you will be able to judge wether it is dangerous or not to pick the hanging UFO.
Do not hesitate to use Reimu A bomb on later part fairies of stage 3.
Practice Murasa's last normal pattern. It is doable.
Take calmer approach on Radiant Treasure Gun and Complete Clarification. The bullets were quite slow actually, and give you more time to predict their movement.
I have more luck on dodging "Cloudy Way in Purple" by pushing my hitbox near the glowing bullets rather than get near the rectangular bullets. The true glowing bullets hitbox are easier to predict.
Try to misdirect Byakuren red bubble bullet on her 4th noncard harder. Don't try to shotgun her.
Superhuman Byakuren is easier if done by not following her. Just follow her on her first wave to the left, then stick there, on the left side. Again, those bullets are slow, slower than RTG, and can be read just like it.
If your focus is to capture all the spellcards/generally do well, then you are on the right track. Summon more Red UFO to practice the full run because you have room for error while the difficulty is not toned down because of bombing.
