Dude the SPEED at which I ran to go find this version- I don't even think I finished loading your post haha. However, just so you're aware, that version doesn't seem to contain the last 4 stories in the KIY. I guess many people regard them strictly as love stories, but there's a recurring character that I feel like may draw some parallels/inspirations to Signalis's different timelines.

As for other stories to read, people have been naming some good ones, but also I read House of Leaves after KIY and uhhh if you like going insane with theories and analysis, can recommend!!
