On your mobile, you can click directly on the screen at the exact point where you want to go or you can use the joystick at the bottom left.
On PC/MAC, to move you can click with the mouse on the point where you want to go or, if you prefer, you can also use the arrow keys or the AWSD keyboard keys.
Additional movement options (dancing, sitting, clapping) are located in the first icon at the bottom right.
