Well, I still have almost nothing besides the grammar tables and a small number of words. I suppose this was kind of a speedlang challenge, but I wasn't taking it as one because it was longer than most speedlang challenges. But, I will definitely continue working on Centahenti, so I'm actually just going to submit what I have and it'll continue to update, even past when the Conlang Jam ends.
Edit: ...Ok how the hell do I submit something that's not a game? I'm not a programmer, I'm a conlanger...
