Great take on the theme! Really nice visuals too.
I like that there's actually a decent amount of clues about which email is the right one, and it becomes even more apparent once you get a bad ending. I'm sure a lot of similar narrative games would make it effectively random or blatantly obvious, so nice work getting the balance right.
I'd love to see a longer game in this style, like maybe something where you have to coax more information from each potential scammer without sharing your own info to see if it's actually a scam.
