Moving around can be pretty annoying with the constant ledge grabbing, so what if you made it so you only ledge grab a block 3 blocks up and higher? Mario can jump up three-ish blocks, so this is probably a good amount to use.
the reason is because in the og sm64, nintendo made the levels in a way that you won't constantly ledge grab however, the minecraft worlds are not used to the sm64 moveset so it can be wonky
