It seems like if what you’re showing is what you understand they find appealing and fun, then surely that’s what should be in the game. You give them that.
But instead, you give them something else that is unrelated to what they’ve seen on the ad? A gem matching candy crush clone they’ve seen a thousand times?
How is that model working? How is that holding up as a marketing technique???
As I mentioned in other comments, I’m a software dev that’s worked with companies that were doing this, that were talking to other mobile game companies that were doing this. I hate to say “trust me bro” but, this stuff isn’t something they’re like happy to publicly advertise so it’s not like it’s written up somewhere, AFAIK.
