Cat #uncompressed

u/tomxor

Nice. You can definitely get this under the 100 char mark. One big saving: If you pack both X and Y into one char it will not only save you characters, but also save you the overhead of defining/calling a function.
u/tomxor

You will probably want to encode the points with -32 applied before you try to bit pack them though.
