But I have a few suggestions, if you don't mind (I realize that this is very much a WIP):
1. Make it so other players/mobs can ride you if you turn into a ridable mob (a horse, for e.g.), and equip horse armors and stuff.
2. Make it so you can turn it off, or "blacklist" certain mobs, or something like that so you don't have to keep deleting them from your morph list, or turn into a Zombie during the daytime while low on hearts.
Yay, finally an official thread! This mod is one of the main reasons I still play on servers, it's just too much fun to not use it. Honestly ichun, this is one of the simpler, yet better mods I've ever used. Nice work!
