I’m currently experimenting with the 8Bit theme from Brutalist Themes . It’s not perfect: I had hoped to be able to adjust the spacing, and I wish the ‘close button’ did something but it’s a fun look and my site seems to be stuck sometime before the year 2000 what with the focus on old RPGs and similar.
Update, November 5, 2024: It was a good theme, but I’ve moved to Hugo from Wordpress for Reasons.
