I know In the descriptions it says it supports controller and I don't see why it wouldnt . But I'm having issues with playing it on my Rog Ally , the buttons don't work at all but of course the touch screen does.

Same problem. The game doesn't recognize my controller at all. Doesn't matter if it's connected when the game starts or not. Simply doesn't read the controller at all. Tried in XInput and DirectInput modes... no dice. Bluetooth controller.
