A.L.I.A.S. (Alias) Flash Game Steam Deck Use Left Stick to move and Right Stick to aim. Also I've used Left Trigger for shooting instead of Right, so you can move, aim and shoot at the same time - with right trigger it isn't so convenient. Right Trigger for jumping and right trackpad (or sensor controls) for mouse actions. Mouse Inputs Keyboard Inputs Gamepad Inputs Mouse Regions
