I am currently making a game on the iphone that is sort of like space invaders. If you don't know what Space invaders is try it out here. What do you think would be the best way to design the controls? Examples... To move left and right - Accelerometer / To shoot - Tap Screen To move left and right - Hold buttons / To shoot - press button To move left and right - Drag the ship / To shoot - press button Thanks in advance. Will appreciate any ideas!
