I disagree. As long as you have enough control, Marisa is easy to use. She's actually good for scoring runs if you think about it. She's fast which means she can go to the Point of Collection before Yuugi's sake even drop more point items fall off of the screen. She's also got a huge graze hitbox which is good for increasing the score multiplier.
Nobody is better than others for score runs. All shot types are grouped individually. Also, I've read some of your posts complaining about clipdeath. I know you haven't probably played SA Lunatic seriously but let me just point this out to you. Compared to Marisa, Reimu doesn't know the concept of clipdeath.
She kinda has this interesting ability to get herself killed on easy and static patterns simply because said patterns are dense. You won't see any of this on Normal mode.
EDIT: Fuck my skills today. They don't work. At all! I even went as far as game over'ing on Route A1 in Fairy Wars on Hard. Does. Not. Fucking. Happen.
Except for today apparently. Off-days sucks balls. Especially when they happen when you are motivated to do something. Which is just about never recently especially since the latest Touhou game didn't deliver the package it should've done. But then I get to play Fairy Wars and realize, whoa ZUN you can make patterns? Why didn't I see that back then? And start playing it. So yeah. I suck today and thought I'd tell a tragic story. Boo hoo, ha ha, fuck. I'm leaving. Of to buy a mountain of Cola and a mountain of something edible and start playing something more relaxing while I ponder on an excuse for why I didn't go to school today.
PS: On the bright side, I did manage a Gold on Sapphire's midboss card in Stage 3. So I at least managed to pull something off today.
