This character mod is super fun! I played through the main campaign with him today and had a fun time trying to make it through some of the tougher levels! Playing as Toad really makes you think outside the box about your approach to completing certain stages, and it was a nice change of pace considering I usually just blast through everything whenever I break in a modded character in the vanilla levels.
There is *one* small issue I've noticed that hasn't been mentioned here yet, and I'm not sure if it's an oversight or if it was intentional. Regardless, I'm going to let it be known here: Crouching doesn't allow you to pass under small gaps that you could usually fit under when crouching/rolling/spindashing/etc, which means that a few pathways in vanilla become blocked off, and certain map packs become impossible to complete without manually changing your size via console or other addons. Other than that tiny hiccup (and one small game freeze that occurred when I tossed a Robo Hood at a Lance-A-Bot in Castle Eggman Zone 2), I had a blast with Toad! Very intriguing playstyle, very entertaining to play as.
