Co-articulated palatalized postalveolar consonants merge with postalveolar consonants to become just postalveolar.
Also, what could be some strategies to make the word longer? Create a conjugation for present participles (if they are still different from the plain form?)?
I thought the vowel in -ing was [ɪ], not [i]... Anyhow, it's not crucial for the game anyways. (It would have survived for page and a half until reaching the final stage of [ɪə̯] just to become an [e:] monophthong.)
