I don’t know what region this is supposed to be in and I already hate the eastern dialects

do you mean ©CV© for the syllable structure because your example word kinda contradicts that

At first glance, I thought that was a list Rubik’s cube algs.

I love this. It’s so hideous

I prefer digraphs (Czech CH/Ch/ch) to compound letters (Slovenian IJ/ij), the half-capitalized version just looks better

What’s shown in the picture is fairly solid, to be honest. The vowels remind me Italian (four heights) meets German (front unrounded vs. front rounded vs. back rounded).

/ʁ/ is being listed twice; is this an accident? Or is the consonant playing double role, as both the voiced counterpart for /x/ and as a liquid?

Vowel romanisation is a bit weird but eh, kind of tricky to do this anyway. I typically reserve letters otherwise associated with consonants for this reason; e.g. ⟨w y v⟩. But in your case it would require a lot of respelling.

Props for using a diaeresis instead of umlaut. It’s the best approach in this case, umlaut tends to create too much diacritic spam.

Main thing missing from the phonotactics are assimilation rules; for example languages typically don’t allow stuff like /np/ or /mt/, even if otherwise allowed. I also think it’s a bit strange to allow coda stops but not coda fricatives, but that might be due to “stereotypical Romance” bias from my part.

I forgot to add that end vowels fall silent when an apostrophe comes before them, technically “KHngoiengngņgöiëxuh’í” /xŋœŋŋngoieʃə/ is completely legal

Did you review the conlang in the meantime? Because the pic says nothing about apostrophes, and /xŋ/ doesn’t seem to be a valid onset in the list.
