A solid exploration of loneliness, depression, and strained child-parent relationships. Very relatable in parts. I do like that you're switching between the two characters, where one is sort of interrogating people to learn about the other, and I'd be interested in seeing a more fleshed out version of this game.
My constructive feedback is pretty much the same as Corrade's below. There's a lot of superfluous text that can be scrapped without taking away from the narrative. I'm not sure if these 'flashback' scenes are yet to be implemented, but I feel the pacing would suffer if the main story takes an unneeded pause. While switching between characters is interesting, you also feel detached to the protagonist when you have an omniscient third-person narrator. I think really getting into Keith's head and seeing the world from his perspective is crucial to the emotional drive of this story.
Keep it up!
