I completely understand your interest in porting games, because I have faced similar challenges myself and can share my experience. When we were transferring the project from PC to mobile devices, we immediately noticed that the key challenge was performance and control adaptation. On mobile platforms, you have to optimize graphics, reduce the load on the processor and carefully rework the interface for touch control so that it is convenient for players. We used modern tools such as Unity and Unreal Engine with their built-in profiling systems, which made it much easier to track down “heavy” places and lags. A life hack that really works: break complex mechanics into separate modules and test them step by step, and use an adaptive UI that adjusts to the screen size and control method. A systematic approach and thorough testing on different devices helped us preserve the visual style, functionality and general spirit of the game, even when transferring large projects. The result exceeded expectations, and the game on mobile devices felt not like a simplified version, but like a full-fledged experience.
