Got it in GOG. It was so good that it made me register here. Good Job! 
So after the Cat Lady, I went and got Downfall too (I'd like to see it on GOG too but what with the last time with TCL already.....). But after I finished it too something just hit me and I really had to ask:
Did Joe killed Susan and Mitzi?
I mean since the timeline of Downfall should've happened just a while after TCL, and in Downfall Joe killed 4 "Sophies" (not counting the final boss) when there's exactly 4 females (including Mitzi) in the apartments; Also three males died in Downfall, while there were 2 living male characters (Apartment 5 & 8) we've seen in TCL (except for apartment 1 which we've only saw the old lady from, and she had a husband too? And I'm not sure but there's also a daughter or not?); And then there's the gutted cat (TEACUP!?)......
According to the endings, it seemed that Susan and Co. had never moved out after TCL.....
So maybe the "Good Ending" really isn't that good?
Might be a stretch, but it seemed pretty plausible.
