The whole town made a big thing of it
This line is worded a little weirdly for me. Not only that, I think this already downplays whatever's gonna happening. You could make this something like "The whole town made a fuss about it." for some better wording, but even then may downplay it.
We were never told why. Not really.
Not really is extraneous. It doesn't really add anything and makes this more casual. Which it is casual, but I believe you would be aiming for a serious tone.
The only real thing we knew was that people would go missing sometimes. Always during the winter.
When you're trying to make this sound more menacing by adding stuff like this in the next sentence, it feels more like you're trying to make this more menacing in a way you would when you're telling stories around a campfire. In my book, a creepypasta is basically like a personal recount of a "creepy" experience. Make it feel personal. Like it really happened to them.
Example: The only thing we really knew was that people would sometimes go missing in the winter.
but you grow up with it and never think to look too far into it. Why would you?
Bit bothered. Unsure what this means.
And I just knew.
Small suggestion for your tastes. But the position of this is a bit awkward for me reading. I suggest putting at the end of this paragraph or the last paragraph so it gives more "oomph". It got me a bit to realise it was meaning the narrator knew what happened to their friend rather than they knew their friend were talking; even despite the full stop.
So, same meaning if implemented. But better positioning for being clearer and possibly making it more powerful.
No one was doing anything about it. Nothing real.
Basically the same as the other critique I made a bit before. Also having this in with the other one would be a little repetitive.
It felt kind of pointless.
This sentence kinda buds in and amps this paragraph down. If you removed this and went straight onto the self questions, the paragraph feel more connected as this little part isn't adding so much.
I glanced around and didn't see much else nearby, but I had to be in the right place, surely.
It looks like you're branching off from "recounting the moment" into "living the moment" here. I suggest changing this sentence to fit the former so it nests properly.
Not too far, but it was a direction.
This sentence doesn't really add much, if not anything. I don't get what this is supposed to tell us and spends our time keeping our tension and walking to the climax to waver. Not only that "but it was a direction." is not honestly a good look here and doesn't make a good tone.
, but it was just the wind.
Paired with the fact this is a recount and not the character actually in the moment, this just looks strange. We know it's just wind; they told us.
More of gap in the forest than anything with the snow piled up around it like a bowl.
Strange wording for me here. Is this put right?
Alright, I'm stopping here. These are just a few examples I pointed out so you can use them as reference. Again, I feel the tone could be more personal to the story. And at times, not all the time, you have small sentences and little bits that don't really add and use up our tension.
If you'd like any further critique. I'd be happy to look again!
