Heh, you managed to swing my opinion a 180 in a single sentence.

>We built a tamagotchi-like app called Piggly that would let you feed and take care of it using money from your bank account.

"Wow, that's exploitative as hell. You won't get many players but there are a few who'd get addicted and basically drain their accounts. Immoral - but profitable!"

>However, instead of treating it like an in-app purchase, the money goes from your chequing account into savings or investments (you decide).

"Well, that's just awesome. It encourages people to save by turning it into a game. If they really end up needing that money they can always move it back."

Neat idea. I wonder how a bank would react to someone constantly pushing money between checkings and savings to care for their Piggly without actually saving as if they had a pet.
