The script is usable in its current state because people have received multiple 99s. Whether you feel like it's human-like enough is indeed up for debate but that's a matter of perspective.
As for methods to traverse; there are 19 different methods to choose from, all with their own options as well, which appears to be sufficient for nearly all users. I'm afraid I can't cater to everybody's needs.
If you're experiencing actual bugs though, feel free to report them to me via Discord.
