Armadillo Run is a physics-based puzzle game. You have to build structures with the purpose of getting an armadillo to a certain point in space. There is a selection of building materials, each with different properties, which can be combined to form almost anything. The realistic physics simulation gives you the freedom to solve each level in many different ways.

Can you try to get a screenshot comparison that demonstrates the extra width of widescreen being used? "More empty space on the left and right" isn't really hor +.
Is the extra width of widescreen ever used in this game? Or is the useful stuff always in the middle of the screen with the sides never displaying more than white background?
