The basic rudiments of the game are there.
You can start a game.
You can complete a game.
You can start a new game.
And from here, I can start to flesh it out.
It has no sound. It needs some.
It has no high scores. It needs some.
It has no runnable jar that can be downloaded by someone and played on their machine. It needs one.
It has no applet on a web page anywhere. It needs one.
It has no help screen. While it doesn’t need one, the depths of mankind’s need for instruction is limitless.
Once sounds are in, it needs controls for muting/unmuting and volume.
It needs an icon other than the standard LWJGL icon.
Showing once again that even a small, trivial game like CTYR involves quite a bit of work to be polished.
