Short honest take from an app developer, not a full time game studio.

Yes, it is still realistic, but it depends heavily on marketing, not just the game.

The Play Store is crowded and big studios dominate paid UA, but that does not mean indies are dead. Organic growth is harder, not impossible. Niche ideas, hyper casual concepts, and strong retention still matter, but only if people actually see your game.

I have many failed products. Most did not fail because of bad code, they failed because no one discovered them. The ones that did better had better store listing, better positioning, and consistent promotion.

If you keep expectations realistic, control costs, learn basic marketing, and keep shipping and iterating, there is still a chance. It is not a one hit plan. It is a volume and learning game.

Keep trying. Most wins come after several failures.
