PbtA games really need playbooks for their DMs (here the Mother) to function properly. The blurb provided is a cool start, but I think it needs the aforementioned GM playbook, Cryomancy skill tree, and racialized glitter differences (though given the player pool is herein limited to elves, the differences should probably be star-sign-based) to really function.
Still, you released this for free, so that’s cool.
