What is the context of the ctr, the context of the google claims, and how is ctr calculated on Itch?
At first guess, I would say, you make science fiction and if your stuff gets shown to people looking for fantasy stuff, your ctr is not relevant.
I would also assume predictions of statistics will not really be all that accurate in this case. You market is not millions of gamers, it is dozens of developers that might wanna make a cyberpunk like pixel art rpg game. This here is about 60 games https://itch.io/games/genre-rpg/tag-cyberpunk/tag-pixel-art
The cover image looks informative. The opposite of clickbait.
