PlaneJam EXTENDED!

I didn't want to modify my original "PlaneJam" since that's the version that I actually finished on the plane. I'm not planning on making it a incredibly fleshed out, but I wanted to "finish" it. Instead of overwriting what was done during the PlaneJam, I decided to create a new project that would receive the updates.

Controls are the same as they were in PlaneJam (arrows to move, space to shoot) and for some unknown reason, it now works in Chrome.
