Hi! Thank you for giving us your feedback!!
We're sorry that in some parts of the game the voices are heard in the sound effects section and not in the voice section, this is because while doing the codification, some audios didn't worked in the voice channel as we planned, and our solution was to place some of the voice lines on the sound channel. But fortunately, this doesn't happen in the entire game, only in a few small sections of it.
We hope that despite having these small inconveniences you can enjoy the game, we'll feel honored if you give this a little chance.
We also recommend not muting the entire sound section so you have a better in-game experience!!
