What you call rigamarole is the standard way to map button presses to tge screen. It only looks like rigamarole to a PC user who is coming to gripa with how a controller interfaces with a screen. A third party mapping utility is STANDARD use case because you’re mapping button presses to the screen. That’s litterally how it works and it works well. When we mobile game players play games THIS is how we play and this IS THE reason why what you call “mobile games” TsumTsum candy crush etc are losing popularity because people be playing more intense games on mobile these days. Because of controller support.
