Took a bit for me to install the script but it does perform really well in-game.
However, one small thing that I've been experiencing is that when using ledges, the dust animation for when the player lands is offset downwards by one whole grid. This happens after placing the animations.rxdata from the download provided.
I tried replicating this in a backup of my personal project as well as a fresh copy of PE and it was the same outcome.
Not too sure if it's me doing something wrong with the install still, so this is still a great script nonetheless.
