How Can an Android App Design Company Solve Issues

I recently partnered with an android app design company to build a customized mobile game. While the design phase went well, I am facing some challenges with implementing certain features inside the game due to platform restrictions. These issues are affecting both usability and overall user experience. Have others here run into similar problems after completing their game designs? How did you manage to fix these challenges without losing the creative design elements or functionality that make the game engaging?
