F9R-Dev2D is a simplistic Falcon 9 landing game. It was originally created as a programming-exercise-slash-fun-toy, and as a result, the code could be far cleaner than it currently is.

To fly, use the arrow keys (or A/D for pitch and Shift/Ctrl for throttle); X and Z throttle to zero and full throttle, respectively. If the pitch direction feels backwards, toggle “flip left-right”.
