Some games don't really lend themselves to either touch screen input or, as of iOS13, controller input. Yet, when available, I'd prefer getting the iOS version for the sake of mobile availability on travels.
So I considered streaming the games from iOS to my PC while I am at home, which works at acceptable frame rates with AirPlay receivers like LonelyScreen.
However, it doesn't fix the controls issue. Is there any way go mirror the PC-Keyboard and Mouse to iOS? Preferably using some "bi-directional" feature of AirPlay, if such a thing exists.
