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???
You’re only about a month in, aim to release on somewhere like itch.io instead of a mobile store. Join some dev communities and game jams and the like. Building up a following like that is a million times easier than trying to get noticed in the sea of SEO games in an app store.
