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.
