The x-height is so uncommonly high it makes it genuinely difficult to distinguish between uppercase/ascending and lowercase letters at a glance (e.g. 'U' vs 'u', or 'h' vs. 'n'), and similarly the descender is so tiny it makes it hard to distinguish certain letters at a glance (e.g. 'q' vs 'p'). The whole point of large-enough ascenders and descenders is to recognize the shapes of whole words before looking at their letters, which these dimensions destroy.
The extremely square aspect of rounded segments similarly makes them harder to distinguish from straight segments at a glance (e.g. 'U' vs 'O' are far more similar than you want for legibility).
Not to mention, italic cursive is particularly difficult to read. Handwritten-style cursive was never designed for legibility -- it was designed for speed in writing. Adopting it in a body-text typeface meant for reading adds work for the reader to decipher it.
I don't want to be so negative, but typeface design has certain principles that the creator is simply ignoring. They're not arbitrary or aesthetic, but rather are directly about functional legibility.
At the end of the day, this typeface goes out of its way to be surprisingly difficult to read. You can read it, but it simply takes more effort. Which is generally the last thing you want in a typeface for coding (or anything body text).
