I'm not sure if this one counts, but I'm a fan of Rogule
Rogule is a minimalist online Roguelike game you play in your web browser. Everyone gets the same dungeon each day. You get one chance to beat each day's dungeon. It is free to play.
I use Kavita and I'm really happy with it. I understand your reservations about the subscription, but I'm not subscribed to the premium features because I don't need them either.
The PDF reader on it is okay, I think. I really prefer reading PDF files. I usually convert my PDF comics to cbz. But yeah, I like Kavita because it's easy and convenient.
I need absolute quiet to read and it's taxing for me to read for long periods of time. However, I'm more an audio person, so I mostly listen to books, and if given the opportunity, I could listen to books all day.
Yeah I figured (as is a lot of businesses making a buck off of supernatural/paranormal attractions) but the look of it so off-putting, so mission accomplished with the aesthetic
I highly recommend using Bull-dog sauce 🤤
