Endless Runner Game World Problem: Desert Food & Clothing Scarcity

In this game, you will spawn in a desert playing as a character named Marko and by using Keys A, D, Left and Right you will be able to control Marko and collect coins (for fun), BUT, you will have to avoid some obstacles (trees, rocks, and crates). I want this game to give people an image of one of the biggest problems this world faces; food and clothing scarcity. This game is still in progress but i hope you can at least see my vision in this game and what I'm trying to demonstrate to other students & teachers around the world.
