Agreed, this is hard to read.

My initial impression was I can't read it fast, and when I try to read it fast then I miss words and have to go back.

If anything, it forces you to slow down. Maybe that's good for people who are learning to read. But for experienced readers, that seems bad.

On the plus side, the feeling of reading this is nice. It is easy on the eyes.

This might be a good fit for educational material. But I would not use this for journalism or literature.

I feel like the lowercase lacks risers, it's kerned too tightly to be legible quickly. It's ornamental but I don't feel easier, it's more difficult to read if anything.

It feels fatiguing to read; and I'm supposedly in one of their target demographics.

Personally I've always found Monospace fonts the easiest like Microsoft's Courier New or Consolas. It feels like you're time travelling back to the 1980s visually, but they're so comfortable to read because your brain can make assumptions which are accurate.

I found it enjoyable to read.

Obviously some placebo effect from the context but it felt fun.
