I wanted to refactor the code and optimize away the unused array indexes, so there is no time wasted checking if they are active or not. I also toyed with the colors to make it look nicer. I removed the middle pixel PSET during forward path, and only draw in in reverse. I made another LUT for middle pixel jumps (length 1 not 2). There is more that could be done, such as removing the REM statements, combining more statements into one line, and removing the need for G-10 if I simply used 1,2,3,4 as the path direction colors. Also, there's likely no need to randomly check for making a new path on each iteration; during back tracing, any such made paths almost always terminate without any work to do.
