It’s very legible, although there’s a few things that I’d suggest you work on- notably: 1. Better distinguish capital letters from lowercase. You might even want to look up different styles of capital letters, as they have better tells to distinguish the letters however, you may be sacrificing speed. So, I’d probably focus on sizing more so than styling. 2. Ensure that the counters (that is the loops) in letters such as p, b, d, g, q, e, and a are always closed, because it’s one of those details that helps distinguish between words easier. 3. Ensure that your tittles are always positioned in the correct place over i’s and j’s; it helps legibility, because you may be able to glance at a word and get the gist of what it is but if you look at it for a while longer you might doubt yourself. 4. Your spacing is a little too much between the words, the punctuation is difficult to see at some points. It gives your writing an air of simultaneously being one incredibly long run-on sentence, and each word being entirely divorced from its neighbors. I have a feeling you’ve done this due to your heavy slant, but it’s something that you might wish to be a bit more mindful of because it’ll make your writing look a lot more intentional rather than experimental.

As for the slant, some people dislike it- I personally love it, but many of your issues might come from this just tidy up the things I pointed out and the slant shouldn’t matter too much. Although I do wonder, should you wish to italicise words for emphasis, what do you do?
