I like the premise, and am curious about what’s to come. The “gap” is a bit confusing to me, as I believe there are certain things that would be ahead of its time, but could be explained through the train and what it brings. I wasn’t sure if it only arrives every 3 years as Erin says at work, because Miq boards it at the end. Does our character experience time shifts as spacing out? Interesting time mystery potential all around.
What really draws me are the bits of supernatural happenings and the dream sequences. I feel the relationships/dialogues are really awkward, though I am trying to chalk it up to Erin preemptively rejecting himself, rebounding onto Miq, and being 19 years old. I am very wary of Miq as he seems to be selfish and taking advantage of Erin, despite being upset about other hookups exploiting himself in the past. If this is how the player should be feeling about this character, you’ve got it. They go really, really fast and it feels predatory.
There are a lot of scenes that are silent, or stay on one screen while the character is talking about actively being in a completely different place. For example, when Nemmi leaves and Erin goes to work, but we still see Nemmi up until the train arrives. Also, I think you mean to tag this with “kinetic-novel” instead of “kinect” although I know you plan to add in choices in the future. Aside from some jarring transitions, I liked how the story built up to the eventual realization for both characters.
