Pros and cons are down below)

Advantages:

So scary! The unsettling feeling from the call is amazing and the jumpscares are unpredictable, very well paced and surprisingly effective! I was on the edge of the seat for the entire time playing this!

Disadvantages:

I think that the choices were too close to each other and seemed like it doesn't really matter what you are choosing that much. I'm not sure whether that's correct but that is the impression that I got, I wish there would be more dialogue routes to pick.

Overall:

I wish this was a full game. 9.8 dispatch calls / 10. That was one of the best short indie horror games I've played and I've played a ton.

Hope my feedback was useful!
