I 1cc'd Touhou 6 - 10 on Lunatic with some practice, but doing that SA Lunatic clear just now might be the hardest thing I've ever done in a video game. I'm still shaking.
Also, a few weeks ago I captured every single spell card in IN as well, including Last Word. The hardest one for me was Kaguya's last regular spell on Lunatic. I did all of TD's spells, too, but that was easier.
