It was made on 9th of august, 2021 and I found it on my Google Keep, where I also put and update Twastoni. At the time I made this version, I didn't really care about letters with unconnected diacritics in the alphabet, but now I do care, so in the second version I replaced half of the letters with acute accents with the same ones but with strokes instead and replaced the other half with IPA letters (which I didn't know existed until that update).
