That's an interesting way to play the game. This is the first time I've heard of running android on a switch.
Unfortunately the mobile build is not designed for that kind of use. It's expected to be run on a phone with a touchscreen. I'll see if I can add a setting to hide the button visuals (the buttons will still be on the screen, just invisible).
Oh, if you have a photo of the game running on a Switch, I'd love to see it! :D
