Game dev and embedded require very different skills but both widely use C/C++ so if you have knowledge from that area from your masters studies, then you could refresh your knowledge in those areas. Perhaps doing some projects in Rust might be another option for you. If you like working with Python then DS/ML/AI might also be an option. Look at the job listings in your area and identify what domains and skills are in demand and then craft a path to get to the area that most suits / appeals to you. Sometimes you may need to take a cut in pay to enter a very different field.
