Great game! I've noticed with the voice acting that more often than not, the twins don't speak their lines. Or they will just say "Yes" or "Listen" but not the rest of the sentence. Is this intended? The actors are great and have nice voices too btw.
Not all lines are voiced - this is partial voice acting! The yandere scenes, some important lines such as the beginning ones and some talks with the twin, as well the endings are voiced.
Edited to add: if we fully voiced the game it would be way over a thousand voice lines for each actor, which would be really cool but a bit too much for my first time lmao
