This episode of Con Critic covers a language named after an old reference grammar: https://www.reddit.com/r/conlangs/comments/12e5iy9/the_tale_of_two_bad_conlangs_hyperfeline_hf_and/
Also, a correction with the letter names, the name of the /e/ letter is actually /se.ɹe/ and not /se.ɾe/, the latter of which violates Twobaddic phonotactics.
