Why is it that the walls on the left and right don't seem to match up with the edge of the screen when you look at this on an android phone in the simulator?

This is because the app is created for an iPhone-sized screen, with "letterbox" chosen in the config.lua file. The reason the walls of the game don't line up with the edges of the Android display is because the app is being letterboxed.

In config.lua, you can change scale="letterbox" to scale="zoomStretch" to see the difference. While not the best choice for the artwork, as it was designed for an iPhone, it will solve the problem without too many concerns. If you were to use "zoomEven" instead, the paddle would be pushed off of the thinner Android screen.
