Your game won't be commercial-quality; that would be unreasonable after learning about C# programming and Unity game development for a few months. It takes my UCCS students 4 years of courses and experience to get to the point where they can build a commercial-quality game in the senior capstone project. On the other hand, building your own game is the culmination of the material you've learned in the previous courses in the specialization.
That's a great thing to do!
Module 1: Develop a planning document for your game
Module 2: Develop a prototype of your game
Module 3: Implement the menu and difficulty systems in your game
Module 4: Implement Iteration 1 of your game
Module 5: Implement Iteration 2 of your game
Module 6: Finish implementing your game for beta testing
Module 7: Conduct beta testing and modify your game as appropriate
Module 8: Complete final peer review
