Good concept. To answer your questions:
- I would recommend showing the required organs on the screen or something so people don’t have to open the book. I had a hard time remembering and had to open the book multiple times per patient which grew annoying. Adding some more variation would also be nice as it got pretty repetitive dragging all those organs in.
- I did not really spend much time in the lounge, I found the font a little difficult to read. I would definitely focus on the surgery gameplay first.
- With some polish you have the basis for a nice game here :)
