New update to A Robot's Journey Demo

Thank you to those who have played my game and left feedback so I can continue to improve A Robot's Journey. Here is a list of additions and bug fixes.

• Add voice over and subtitles to monolith interaction - Add a Feedback button on main menu that links to Steam forum - Move trigger at end of demo to prevent player from finishing the game without activating the 3 lake platforms. - Remove zoom camera functionality - 'press backspace to skip' now fades away and no longer remains on screen - Add functionality to 'Brightness slider' in graphics setting
