These are interactive stories, there aren't any real game play, it's all choosing dialogue. There used to be children's books like that, like Goosebumps interactive stories where you make a decision and then flip to a certain page to continue, it's basically a digital version of that but with cinematics instead.
The point of the game is you make decisions and it affects the story as it unfolds, and your story can play out very differently depending on what you choose to do. The good thing about not having actual gameplay is that the story isn't as restricted as your average game, your decisions could lead to a completely different path. I think most of their games you can download the first episode free on your phone to try them out, Wolf among US and the Walking Dead are probably some of their best.
IMO, don't play this when you feel like playing a game, play it when you feeling like watching a movie, this is a cartoon that lets you choose what happens next, it's kind of neat in that sense.
