Ngths definitely sounds nice when interpreted literally in the ipa /ngths/

There are other weird things in English. Like ghost letters influencing pronounced letters like Cake being/Kākᵉ/

Yeah

Also with things like ough, which is pronounced many different ways depending on external factors

Yeah. Also, there are languages that also have consonant clusters like English. Dutch has Slechtstschrijvend. Polish has Szczebrzeszyn. Georgian has Gprtskvni. All languages have a few weird words. It just that English has an absurd amount of them.

True

In my conlang ive limited the consonant clusters to a max of 3 consonants (and this can only occur in coda position). most of the consonant clusters are just 2 consonants (sk, pr, kr, fn, pk, pn, sg, etc.)

Also have you heard of ilothwii? its a polysynthetic conlang made by biblaridion (a conlanging youtuber) and it has absolutely ridiculous extremely hard to pronounce clusters (qthlgwlm)

Also, the conlang I’m making(Smāic) is a poly synthetic language but to prevent words from getting ridiculously long, base words are limited to 4 letters long. Also, I listened to the Illothwii video and the pronunciation is really hard.
