Generally, the first piece of advice in Battle Royale games is to know where to fall. But since this is a game to play on a cell phone, you first need to know where the controls are. Look for "Settings" and then "Controls". You can customize your controls by dragging the different buttons to different areas of the screen. Choose a Layout that is comfortable and intuitive. If you play on the emulator, do the same thing, mapping the keys you prefer to play with.
