I, Funnyman, who originated from the Alphatale Discord, Love what this AU is going for, and I'm surprised to see how popular it got in such a short timespan. But for me, the story is all over the place.
The problems: It recaps everything too quickly and does get a bit Incoherent. to give a general idea of what I mean, I'll just give this snippet: "KM defeats Ten and in result frees everyone and as soon as it's done Omni returns and Tell them all about what's happening in the TransVoid and in an attempt to get everyone together begins to tell them all how much each of them has grown and how they must put they're differences aside and work together."
This is how the AU opens up, a recap of King multiverse fighting Ten to free everyone and all these events happening all at once. there isn't that much Tension or explanation for what's going on, and while the events may seem cool and all, It's better off to add more to this and explain the events transpiring. Have the beginning start with some tension that leads to fight with King multiverse and Ten, with dialogue and character interaction that leads up to the battle.
as a decent story writer (As I am planning to make an indie game in the future), I can help edit the story for any Inconsistencies If you'd like me to, but that's up to you guys.
