Well, many games here are more fun to make for the creator than they are fun for players to play. It is nice to have a creative hobby, but the competition is vast and player budget is limited. Indie games excel at genres and topics seldom used in AAA games. A reason why horror is so popular (on itch). The early professional games were often platformers, so there is a plethora of polished and established platformers. New platformers are measured in view of them. And technologically, if a game is basically simpler than early Mario, it is not gonna impress people all that much. You could try story, or appeal to some retro enthusiasts, but that is a small market.
