There is potential to make this more then what there is, unlike others I'm not too bothered by the game graphics, if you are good at using your imagination, you can think about how the interactions and the area looks. Thou with that in mind, I do suggest you clarify in the description about the low graphics so others are not too disappointed.
Also there could be more interactions and more characters put in here and more to do, like different ways to end the game, different choices of reactions when you interact with others, and those interactions having an effect on how the game ends, more to the world itself, and more.
Regardless, with a little more work, It can be a good story driven game.
