WGJ238-UFO

I don't expect my contribution will be much of a competitor, but truly I'm the only target audience. I rearranged my coding schedule when I saw the theme, and spent my free time writing a game engine in C++ with SFML. 

Though it doesn't look like much, I'm quite happy with how the input handling, scene management, and entity, components, systems code is shaping up. I only spent the last hour of hacking on gameplay.
