The principle of that experimental game is basically nothing more than dragging an orb into a gate. Seems easy at first sight, but is not! The orb follows a Psyline, which it's bound to and which the player is able to draw. Apart from that the orb underlies the physical laws, which make it harder to let the orb reach it's goal.
