So far my game has been the strictest of 2D affairs but recently I was working on a scene with mountains in the background. It suddenly occured to me, why on Earth couldn't I 'get to' those mountains? They were being designed as merely background objects...to save the player from the monotony of blue skies :)
Seems so obvious now but I really need to adhere closer to the 'if you see it, you can get there' design philosophy. Of course given my development and design team of 1 I might not reach too dizzying a scale of depth just yet but its something I need to work on for sure.
Working on adding some tintilating background art now that will hopefully inspire deeper exploration of my little game world!
