Update notes for august 19th

A new element has been introduced in Level 3 - the Labyrinth Level. It is called 'Hidden Entrance Overlay'. The ELement reveals the game object underneath or clears the way after it was active as a barricade. Depending on the game class - which is chosen randomly - Ballooni has to hit the element with his spells, collect a certain number of coins or just get close to the element to trigger it. The classic digital directional pad of a gamepad/controller is now also supported.
