I myself faced the task of porting a game from PC to console and mobile platforms, and to be honest, it turned out to be both exciting and difficult. The first thing I encountered was graphics and performance optimization: the game ran perfectly on PC, but on mobile devices and consoles, some scenes slowed down. To solve this problem, I began to actively use profilers and resource analysis tools that allow you to identify bottlenecks and properly redistribute the load. The second point is the compatibility of the engine and controllers. Here, documentation and specialized plugins that integrate with the main engines and automatically adapt controls to different devices helped. Particularly useful was a visit to https://devotedstudios.com/ They describe in detail proven approaches to optimization, compatibility and porting, provide specific tools to speed up the process and reduce errors. Thanks to this, my experience became much more productive, and the quality of the game on all platforms remained at a high level.
