Just a heads up on limitations with a JavaFX game engine: If you make it Node based, the lack of explicit z-ordering is a pain in the but, and if you make it canvas based, erasing can only be done in rectangles, not paths (which works fine for sprites, but if you wanted to allows generic shapes you'd run into issues).
