Private static final int INIT_BODY_LEN = 5 * that game could be re-played at a higher speed. * Another "future" would be to record "events" during play so * difficulties on slower machines (perhaps not?). Paint currently works on my machine but may have * Use a backing image for grid to make paint operation more * When the length gets to 200 the speed increases slightly.
This works well so I post this just for you to enjoy and perhaps learn from. I played the Snake game on an ASCII terminal 40 years ago.
