Damn, real shame how things turned out. I went ahead and tried out the new update with the translations as is, and... Honestly somehow the "caveman" dialogue bothered me less than I thought it would.
I'd describe it like every 3rd or 4th word in a sentence of dialogue is missing, and it somehow worked alright for speed-reading. I don't doubt I'm missing a lot of context and nuance to the story though.
I do like the AI CG's style here so that made up for things a bit. Fair bit of content in the new version too. Here's to hoping the author can find a compromise to continue their work - even if it's letting fans help out with the translation.
(By the way, anyone know any other games with similar AI style graphics? I'll check out even the ones with shitty story/gameplay) (been asked and answered earlier in this thread)
