New Version 0.5 - Key mapping and new levels

A small update with :

• Added settings menu for Sound, video and controls
• Added keys mapping (unfortunately I needed to remove gamepad for now).
• Added two new levels (Illusion and The Frog).
• Added new ability, "toggle light". Enable you to glow your cubes to be able to follow them in the dark (only available in level 7 for now).

Hope you'll enjoy this update :D
