I've started the game, and followed the tutorial. But then my residents started dying. at first I didn't notice until I died down to 15 residents. I tried to figure out what was causing this, but then I just wanted to keep following the tutorial for a short while until I suddenly died down to 2 then 1 and now none. I didn't find out the reason why everyone died, and the duration of how fast everyone died was too fast.
It could be because I sped up 4x, but somehow there is no system where you are quickly alerted to the problem.
