Hey thank you for your message! For the moment I didn't plan to add any voice acting to the game because I want to pay properly each voice actor and I am the kind of person who like full voice acting ^^"
If the project is a success I will consider raising fund to pay voice actors and make a (free ?) update with voice acting! Although, i don't know if I would like the voice acting to be in english or in french (the original language of the game...), anyway, were are far for this goal yet, I need to finsih to write the script first!
