Wooow! You did much better than I did in my own games runs :-)))
Unfortunately I had no time for implementing a winning condition. Have any suggestions of how this could have looked like? Ms Nightingale was able to reduce the death rate from 42% to 2% by making several improvements. Maybe if there would be simulated years, this would be an achievable goal - as fatal cases drop the more upgrades and experience the player has. I expect your victims died more in the beginning, am I right with that?
Anyways - thank you for playing and sharing your success!
