Plot Twist - Interactive story app

So, I've never seen Black Mirror Bandersnatch, but from what I've heard, it's an interactive Netflix experience where the viewer's choices influence the character's outcomes. That inspired me to think of an app that offers users stories and the ability to make plot choices and see how their choices can influence the plot of the stories, kinda putting the reader in the middle of the experience. Another objective was to try and design the UI in simple black and white (heavily inspired by Pablo Stanley's illustrations on Open Peeps) to see if it'll still hold as much value as if it were in colour... and a few people actually told me they'd be interested to see how this pans out. Fingers crossed?
