I love the level of polish you have in this game. I also appreciate that you can either move with arrow keys or by simply pointing and clicking. Since it's a story game, I'll give some tips about that. Feel free to take it with a grain of salt as everyone has different preferences!
I don't think you need to hold the players hand as much when conveying the mystery of the story. You can trust the player to be curious. For example, when you find the "dont trust them" tape, I don't think it's necessary to write "don't trust who?" or anything like that because the player is already asking those questions.
I didn't fully understand why the hospital was untrusworthy/unsafe. Some cutscenes made it sound like there was something really messed up going on, but then you just... wake up and everything is normal? Perhapse I missed something in which please tell me so I can revisit it.
Overall, I had a good time. It had more content than I was expecting. I liked the art and the sound effects a lot as well. Great job!
