We used to have a series of videos on the San Jenaro Coop twitch channel (incidentally the same group that helped Erik run the Brinkwood crowdfunding campaign, if you are familiar!) but, unfortunately, those VODs expired a while ago. I feel like the latest version of the game has a much healthier collection of random tables and prompts, but I definitely agree it needs even more and we aim to have that done before the project is final.
All that said, I will be running some playtests of the game to celebrate the new version releasing this week, and depending on willingness of others and technology we might record them.... this is far from a promise, it's a distant possibility at best.
