I've been finding more time to read this year, so I already finished one card and am almost halfway through another. (This is less impressive than it sounds, as I think ~13 of those squares are works under 200 pages.) The first card is all hard mode (sans the Cozy Read square), and the one I'm working on now is (almost) all normal mode. (I didn't want to read Harry Potter or A Man Called Ove, so those two squares are going to default to hard mode.)
Normal-only is surprisingly challenging in places (LGBTQIA+ Lead without a significant romance? Steppin' Up with an MC that does become a ruler?).
