Just finished this in one sitting - it was good! Definitely carried hard by it's atmosphere, but it told a complete, solid story with some interesting turns and one stand out scare, which you can't really fault for a free 2 hour experience.

Where it falls down though are the chase scenes, which are super generic and often frustrating/unfocused feeling. Given that these segments are the most gameplay heavy parts of the demo it does unfortunately tarnish the experience a little.
