Brief instruction: each time the cursor is visible, you have to carry out an action by using the following controls: the “simple click” – find a hot spot and click on it. Keep the button pressed to continue the action. The “double click” – you find a hot spot and you proceed as with a “simple click”… but when you release the mouse button, the cursor becomes visible indicating that the action is not finished. That means that you must quickly find a second hot spot. The “click and move” – find a hot spot and click on it and then, without release the mouse button, move your mouse in the direction where the action must occur. The “come and go” – works like the “click and move”, but the mouse movement must be a coming and going action.
