I must say, I really really like this game. I wish to think that the Protagonist we play as isn't as reliable as we think, like the Hospital IS twisted, patiens are negleted but maybe the horrifying nurses and mad doctors is just in the twisted mind of the protagonist.
Anyway, I really REALLY like the look of the hospital and the graphics as a whole, the PS1 style graphics give that semi uncanny feeling which fits this game in a great way.
The soundtrack too is very fitting too. I love how the transition theme sounds (something missing from the soundtrack BTW) which is very slow and deep, feeling like of a desolated place which I'm sure was the intention. I also like that each track of each charecter are the same but with slighty variant, for example I love how Randolph Hide theme, is very mellow and almost calming, something you would've expect to hear in an Doctors Office if it were the 19th century and the Chase theme keeping the same same notes and tempo but sounding more hazy with (i think) more echo almost as if hearing a song as you go unconscious.
Nurse Heideltraut theme is also very good, with the clock remind me of an waiting room but with the song it self almost sounding like a lullaby but well scarier and the Chase theme here, I almost thought the clock was ticking faster but was surprised when at a closer inspection I discovered the clock was ticking at the same speed as in the Hide theme, the only difference was the music which got much more distorded and each time crescendoing and well I must be honest here, I just imaged this sounding like twisted clown music.
Going with Gameplay/story I do like how when you first meet the doctor his voice sounds like a compitaltion of all those like medical commercials where it quickly states the warning compiled all toghter, I REALLY neigh, I LOVE how the first time you go too far from him he doesn't like instantly end you like generic bad guy number #59273 but instead he reassures you everything is fine. It was so surprising the first time like totally got me off guard and well, got my liver removed (or maybe when he said that he actually ment is as a legit medical operation who knows!), still after that innitial scene with him I must say, the puzzle here if we can call it as such is too easy, I was never scared like one of those horror game youtubers that totally don't fake their reactions, while I did like the execution of it, I must say the puzzles as a whole aren't entertaining, I am entertained by the charecter and locations but not by the puzzles themselves (Also the "Don't sit" line is funny as hell)
I do understand the horror comedy vibe you are going with and I must say you pull it off very well, the negleted patient was an fun charecter althought his puzzle was very annoying, I didn't enjoy that in the slightest same with the Nurse which I already described my admiration for soundtrack (and design too) but I really never felt any fear or horror from the antagonists themselves, maybe it's because it's a demo but from the two antagonist we saw it was either very easy and unthreatening or Impossible to beat if you were caught, neither are much fun. my suggestion would be to have these charecters in the spotlight longer, discovering stuff with the ever looming threat of the doctor finding you snooping around in places you aren't supposed to be, discover a bit of lore and who is this doctor and doing puzzles with him looking around for you, and ending with how we ended with him on the demo. Simmilar aproach should be done with the Nurse (maybe even the negleted patient).
These are just my opinions toh, I enjoyed this demo a lot and hope the final product is better then the demo we were shown, good work and good luck.
