i loved the trivia bits during loading. sometimes they faded out really dark and were hard to read. would be nice if there was an sfx or music change when loading finished since i’d moved to another window without realizing it finished.
the lighting outside the manor seems a bit bright for the mood but maybe just a web issue. voice acting was really funny, i liked the cheesy lines.
i think you have the same annoying bug on web I encountered in my own game where your mouse teleports sometimes which can be pretty annoying, might want to add a check to dampen impossible movements.
had a pretty big lag spike when jumping into the operating room but otherwise it performed pretty well.
Overall I think the was a great time and played right through without thinking about stopping. nice work!
