I noticed you're making a lot of small and simple games, and that's totally OK... I won't stop you. But maybe it might be an idea to focus on making more complex and well performed games. I, for myself, felt that making bigger projects and facing harder problems improves my skills. (And that's fairly logical now that I think of it)
But keep going on the good work
This is good advice, but feel free to do what pleases you. I find that if I act on a suggestion of some sort that I don't really want to do, I end up getting demotivated and not learning anything at all.
