As I'm moving through the Elephant Collection this is the one that's impressed me most so far- the Cataclysm on the roof being so shockingly out of place is so unbelievably funny and the Hot Coffee mechanic is incredibly clever. The Elephant Collection has made a change to it but back on browser you had to open the game in a second window to get certain achievements. It's an incredibly cute and clever bit of code and it's always stuck with me for being so charming.

This would be a 7 but it gets an extra 1/2 star because the Cataclysm terrified me as a kid but is fucking hysterical as an adult.
