There is a ton of love and care put into this mod, and every character brings something unique to the table with their moveset. It feels genuinely fun just traversing and moving around the world with these characters, which is the gold standard for a mod like this - it captures the pure essence of fun through movement that Mario 64 did when we all loaded it up for the first time.
The voices are fitting, with two notable exceptions - Rosalina, and Birdo. For Birdo, the performance is fine, nothing wrong with it - to this day there isn't a Nintendo release where she speaks with a human voice, so it's a bit jarring, and doesn't quite click for me.
For Rosalina, it's clear a trans woman was chosen for the role, and as a trans woman myself, this is not a good voice fit. It's clear that she understands the character well, and put her best performance forward. It also immediately sticks out - the timbre of the voice is breathy, but not feminine. It does not fit Rosaline to have a male-sounding voice.
Other than these two wrinkles, this mod is excellent. Please continue to keep up the good work.
