There is a lot to like in this one! A massive step up in overall quality from your prior work. However, I do have a few criticisms and compliments towards the game (I summarize them all in the final 2 or 3 minutes of the video).
Basically, great job with not overdoing the graphical effects. I loved that the hospital was able to be fully explored. Good tension building and effective scares when they do pop up. The biggest issue is a lack of anything happening for a large chunk of the game after you get past the opening minute or two. A little bit more lore or things to look at as we progress through rooms would do a lot. Overall, a great step in the right direction!
