CodeChef is a not-for-profit educational initiative started by Directi more than a decade ago. We started with a dream of seeing an Indian team winning a gold medal at the ACM ICPC World Finals. In its quest for the same, CodeChef has built a self-driven community of the world's best programmers. Today more than 1.3 million competitive programmers from 180+ countries learn from CodeChef. CodeChef has been hosting monthly programming contests regularly for 10 years now. Its platform has assessed 92 million+ code submissions to date, and over 30000 organizations are being impacted by CodeCheffers worldwide. It also organizes SnackDown - one of the world's largest global programming competition whose last edition drew participation from 140+ countries. Since 2017, CodeChef has started providing India's only industry-ready certification in Data Structures and Algorithms, and 1800+ programmers have been certified under the same.

That being said, I wouldn't push it back that far. At best, push it back a month, and spend that month on sololearn.com focusing on the Java courses.

Watch this video by Game Maker's toolkit to understand Unity, after that, learn C# using SoloLearn, it's a Duolingo style (mobile/web)app that teaches programming languages. When you finish both, start doing your own projects and when you don't know something look for documentation, if you don't find any, then search on google, if you still don't find how to do what you want, then you ask on Reddit and StackOverflow.
