Here is my proto-phonology for the chipmunk language I will be working on, this is what I am starting out with and will be evolving the language to add some quirks.
A syllable can, at maximum, be a CVC but ejectives aren't allowed in the end of a syllable. Also at proto, there is vowel harmony where a word can have either all high vowels, are all "low" vowels (labeled here as non-high)
