I think to improve it, instead of each time you interact for it to be a fixed amount of time before the dialogue stops showing, it should instead be a button to press to continue. Those who want to stay and look at what it says longer can stay. Those who already saw it or want to continue can press it to continue faster. I noticed I often would want to continue in my case, and I think it slows down the gameplay. For others, it might actually feel too fast in some parts.
Other than that I really liked the visuals, the controls worked really well and the writing was good - nice job on this!
