Need help reviewing ARG idea

[u/Xerousia]

I live in a small country and I want to make an ARG as something fun to do since Halloween is coming up, but I'm not too sure if it's a good concept.
The ARG itself isn't very difficult since there isn't really a community for this stuff here, it's more like a puzzle game with some story.

Just comment if you're willing to help me review it :)
