Haha, well, my secret was sort of simple. I realised people not assigned to a bed would not die, so before I begun working, I made sure I had a lot of food, wrote a few pleas and then started upgrading beds to max level. I would never assign someone to a bed that was not top tier. So more and more, I could assign people to a pink. Many of the more healthy patients didn't require much, if any interaction, from me so they were assigned, healed and moved - at which point I assigned another one there at once. The only deaths I had was at the beginning of the game and then it was a breeze saving lifes. :D
Aaah! Naw, sorry it didn't make it into the game. :< It looks very nice! But don't feel too frustrated about it, the game is already so good - but I look forward to trying it again when/if you get around to update it post-jam. I would have to switch tactic. ;)
