To start things off, I just want to say that this is a really great story. The plot is amazing so far even with only for chapters and I love the narration. Most people have trouble writing in third person but this writer did very good.

I love how when writing from Willow's POV, you have her thoughts as childish and naive. It's perfect.

There are a few errors, but every story on wattpad has these.

The idea where Slender speaks through the proxies is very good.

I love how the girl is very smart. It just makes sense and goes so right.

To be truthful, that last chapter with Masky and Toby wasn't the best. It was just so different from all the others. It could have been because she was older, but it felt.... wrong. Yeah, it felt wrong. That's the best way to describe it.

All in all, great story. Keep it up!
