Is this project dead?

when prologue will be playable?

I was at the part where Touki nearly trips on a cat on his way to school (I think?) and then when I click continue to the next message, I get this error. Even after loading a previous save and starting over, this error still persists and I can't continue. https://steamuserimages-a.akamaihd.net/ugc/1620689931920260797/B8F3130E8D0BE972BD18DF541E6551484F893211/...

I got to the 3rd episode where you meet the new transfer student with gray hair, and now I can't play anymore.

so i went into the options and saw that there was a hentai scene in there. is this what we will see or am i seeing things
