Thank you for the provided detailed information.
"It's only on the camera" : yes, that is the correct mechanic for this button and function
"choke/shake her head" : these features are done manually (as described below), or auto (if in VR mode, or if turned on the Auto button on the right side of the screen, play button icon). I assume auto was on for the sequences you remembered, which probably created a misinterpretation of the controls. I could try to add shake phone for shake girl, but not sure about choke..tilt phone max to right?
- choke (manual controls) : tap and hold on girl's head then drag her head to the furthest right of the screen, while keeping finger pressed)
- shake head (manual controls) : tap and hold on girl's head, then move your finger (and her head) to one direction (left or right) then oposite then back in other direction (she should start doing some emotions/reactions), can release the finger
Side note: feel free to check the ? (help button) on the top right of the screen for details on each button and choke/shake functionality
Cheers,
