I decided to replay this, because it’s just too good
but anyways, quick guide on the good endings
3: follow the answers guide, call marci or tiller, help anna’s children, and while talking w the guy, choose diplomatic and choose all the options on the right
10: follow the answes guide, call zivil, follow the answer guide on zivil
11: follow the answers, call m or ti, buy the code, let him save you
12: same thing as above, but choose to save him instead
hope this helps!
