You know, I thought this game was pretty dang good.
Yes, it's short; but what it does is keep you guessing.
As a disclaimer: if you're triggered by things such as pedophila, murder, suicide, etc. I would avoid this game as it is not for you.
It seems like a "jumpscare" type, but I promise there are none (in case that's a deal breaker for you). Though, it may not be a jumpscare type of game it definitely leaves you on the edge of your seat holding your breath at times.. just waiting for something to happen.
Side note: If you like mobile games, might I also recommend 'Duskwood', but I digress.
I got this game on the PSS for less than $5 as a spontaneous buy and even though I enjoyed the game and completed it all in one go, I would not say it was worth the original $20. Definitely $5 at most. For $20 I want a game that lasts more than 20+ hours.
Overall- personally, it is a great game that left me thinking about it for the next couple of days. I'll probably play it again in the future. Buy it now while it's on a discounted price.
Spoiler alert:
The connection you develop with the character on the phone was a really nice touch.
