Alright alot has changed with Seek. I wouldn't say it is an EXE or a full-on creepypasta, but you could call it that. I will first try to make a fake gameplay animation first and see if making a game would be ideal or possible for someone as inexperienced like me.
Right now the surface of the story takes heavy inspirations from coraline and godzilla NES creepypasta. Seek is an abomination and a monster that tricks young childrens into thinking it is a game they have played before, then proceeds to kidnap them. Once they start playing, they are introduced with a non-existing title called "Sonic & Tails - Adventures". It might seem "Somewhat" normal at first, but it is all an illusion to ensure the victim that the game is just a normal game. The illusion are entirely based on how the victim remembers the characters, so if someone were to watch them play and focus on details, they would be able to spot flaws with the colors, appearance, and such. The catch is the longer the victim plays, the more distorted the illusion becomes, and the weirder the characters will become, until they are no longer recognizable. The Tails character, however will have its whole demeanor change and shift into a monstrousity that actively pursues the character, or ignores them and tries to take the victim straight away. Victims are added to its mass and have their faces permanently imprinted in the game. I will attempt to make seek very mysterious and avoid humanizing it at all, cause that is what i believe was one of the bigger flaws with the old story.
This is the very simple and obvious story as it appears on the surface, but the real story cannot be told on itself, and must be found.
I will under no circumstances tell what it is to ensure the thrill of finding the truth isn't ruined, so don't ask me or take whatever anybody says as the real truth, because the story cannot be told on its own.
Keep in mind. The old stories, including the one in the wiki are completely outdated and irrelevant, and no the sonic universe is not connected to this story, because that would not at all make sense and end up making the story unorganized and flimsy. It was kinda funny to see it be tagged with 'In-Universe' though imma be real lol
