There is a small amount of pets available, whose you need to find their pet food to be able to try taming them.
Some of the pets are obvious (like the bunnies and the dog), but others are a bit more tricky to find their pet food.
Basically, check a pet food item description, because they will tell which monsters you can tame with them.
As for the absence of guild master right now, the guild doesn't simply "manifests". When the first member is recruited, isn't a ghost adding it to the guild. It's just that the guild master is not a playable character right now, but I will work on it in the future, once I formulate how the guild master and their classes will work (currently, I only got a Human Fighter and Mage drafted, with the Female sprite needing work).
Interactions with Guild Members is something I'll have to add. Would be nice to hear what guild members have to say, and also what they think. And also know more about them too.
Yeah, the new passive from the musicians really makes them handy (beside on the released version of the game, it's also buggy, since even ko'd they can still offer healing). Maybe it might get nerf in the future, but at least they made the musicians even better regarding support, so Kiki can get some rest.
