Don't listen to old folks, you're able to ship quality code production ready already, uni won't make you a better engineer comparing to a self taught path that you have already started and have made results with. The more you make money young the better it will compound through the years the earlier you can retire. Focus on making money, not degree. Keep this creative energy, bootstrap more projects, continue to bring value to the world... It will pay off. You're obviously talented, following uni will end up wasting your time which is highly valuable at that age.
