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???
One of the funniest advertisements I've seen on youtube was basically someone on tiktok going "Okay, I'm gonna try this game out called 'Insert Incredibly Generic Title Here'. Is it a fake game? Let's see." 10 seconds of them playing level 1: "okay, I blew up that barrel and got some coins. Looks like it's not a fake game." And that's the advertisement: Our game is a game that actually exists and isn't an appstore scam.
