This is a snake / nibble clone that I made as some use of free time. It's one of my first games. I think I've fixed most all the bugs, but if you find any please let me know! Oh, and as far as I know, this only works for VB 5.0 and VB 6.0, I haven't tried any other versions...

The user doesn't need to know much, just that you use the arrow keys, and that the form needs a timer.
