Sounds like you are on the right path. Keep in mind you are competing with plenty of game devs world-wide. Since you’ve made a few games already, when working on your next project, try to make something that will stand out from the rest of the games.
I took a look at your games. They look good as a first-time project, but not something that people will spend a long time on. You can explore options like monetising with ads, but I’d suggest you strongly focus on the game itself, to learn the right techniques and make games that are more engaging.
I know its hard to judge something you made yourself, I’d say try to find friends/relatives, that are not afraid to be honest, give them your projects, and ask them for feedback.
My advice would be, keep making games. Try to make different games, to explore different genres and ways of making them.
