Only free script I'd trust on my main. This thing is legendary.
ANYONE HAVING ISSUES:
As stated by people above, the script will often not work on the first try. For me, when doing Monkey Madness, it froze my client and had to shut down the process in windows process manager. The fix for this is just to get to that puzzle, open it, then hop worlds a couple of times. the puzzle's order will change, and if this has been done a couple of times then you can start the script and it will work flawless. Hopefully this solution helps.
and a huge shoutout to all the peeps above me who mentioned this fix. just hope new comers see this without having to dig through other comments
