How to stop control from going negative?
Ohh no...
you need a lot of funny titles
some of the titles can give you BIG bonuses to control
on top of that you also need to play on lower difficulty
Warden with titles should be able to go into Positive control in 1st floor
Prisoner can only get positive control after happy ending and if you had a lot of money for ugrades
at floor 2 and 3 you can get positive control with high level visiting center
if you are on New save and have no titles, you can get positive control on Secretary
you need to upgrade bed, repair mess haul and improve guards
Once bed kick in you should get Beautiful warden title which gives you +1 control if you equip it for all day
from here you can unlock a lot of things
i recommend moving forward in time to day 300 on 100 control for 69 days
and accumulate like 30 000 gold for future needs
i unironically started playing after getting Anarchy (30) floor 1 and birthday cake
There is also a build to never have riots, riots in prison are game-killing if you don't deal with them fast, so build for level 1, 2, 3 that turns off riots is big boost to stability of the prison
if you can get Happy ending, you can defeat final boss to end all riots for you, i often use it because riots are hard
