For the content the game has so far,
I think it's a good start. I can definitely see the future plans to adding more characters through the Heroine/Hero, Riker, and the Lion-Phone guy.
I do find the start a bit rushed in. It's nice to have some ambiance, fluff, and backstory to give the Hero/Heroine some character that's not from just from choice boxes alone. Some people might hate it, I think its a personality builder. You always got to balance the aspects of the story. It might also add some unexpended moments for Riker and perhaps some other love interests if there are plans for them. We do have context that she's independent and is working a bar-restaurant and we have a friend in the phone. But other than that, you can definitely expand a bit on that.
Riker has a great start off. Starts off as a customer, turns and whisks you off. As we continue to spend time with him and depending on the choices given, he can be unpredictable, obsessive, and unsettling. I do find the mini-jump scares interesting. It gives him a sense of mysteriousness that there is something more to him that is missing.
Hopefully in the future update you'll expand upon that idea.
