Hi!!! I'm KT, one of the devs. I'm so glad to hear you enjoyed the game! The choice to not allow the player to interrupt the mother was very intentional. We wanted to portray the mother as overbearing in their relationship so much so that she never even notices the child's submissiveness. A huge narrative goal was to portray the feeling of intimidation the child has through all aspects of the game, not just dialogue.
Thank you so much for playing our game! We are still working on bug fixes, and we really appreciate this feedback!
