Uploading on Gensokyo would probably be better. replays.gensokyo.org. It renames your replays so it doesn't conflict with those that we have.
Start with 3 lives first of all. In any situation where the attacks are aimed at you from more than one angle, only move horizontally. Moving vertically tends to get you killed

I'm specifically referring to Meiling's non spell card with the 6 monsters firing aimed blue kunai streams.
Don't be afraid to bomb Meiling's final spell card. It can get rather hard.
For stage 4, you can actually tiny dodge your way through the aimed white bullet streams. It reduces the chances of random deaths.
Stage 5 - learn to stream more. On Sakuya midboss, she has a safe spot that makes her non spell card relatively trivial. It's directly above her. Check out some replays, you'll probably see it. Also, you're doing Misdirection wrong. You want to stick to one side, and tiny dodge her attacks. Every single one of the bullets are aimed.
Overall, you could definitely learn to bomb more. You lost a lot of bombs that you could have used, and you died a lot of deaths that could have been easily avoided by bombing.
