Alex wrote about how the experience’s physics and mechanics are surprisingly challenging:
It’s the kind of game that’s infectious to watch, but the mechanics are surprisingly quite difficult. You’re essentially playing with two parts: the face, which is controlled by clicking and dragging with the mouse, and the tongue which is controlled with WASD. Moving the tongue is a bit like moving a shopping trolley. It has a substantial weight and is prone to flopping out of the mouth, or onto the wrong trigger point entirely.
