The biggest challenge with mobile game design is not so much the precision of controls, it&#x27;s the premium on screen real estate.<p>You have to put all the information of your game on the same layer as the controls- meaning your number one concern will be optimizing your interface and controlling the flow of information. It also means that the games you&#x27;ll be making should be unique to touchscreen- games ported from other platforms are almost always inferior, in part because their design is optimized for a different platform.
