I love the way you tutorialized the "interruption" mechanic. I would weigh the option of showing the player how much time they have left to answer before things move on without them -- think about The Walking Dead and especially Oxenfree; the latter game especially sought to make silence as meaningful a choice as any other dialogue.
I applaud you for getting all of this done in just 48 hours! I'd love to play a polished version once you have some time to come through and touch stuff up.
Great work overall!
