the bug was in the browser version
I have just tried what you mentioned and was unable to reproduce the bug. When I click on the screen, and don't move my mouse, I notice that the hook/tongue is actually following the direction of the position of the mouse click. I've tried it in different browsers and still can't reproduce it. I am not sure if it's a resolution issue that's causing it.
If you don't mind, could you try it out once again and let me know if you are still seeing the same bug. Thank you.
