At first glance, this game is a bit silly. I mean, you're an anthropomorphic dog, who wants to be "a good dog" and follow the Code of Man.
But we played for the first time on Thursday night, and it was surprisingly fun. As I can tell, the engine is a simplified and modified D&D 5E. I'm not very familiar with 5e, so not too sure about that. It is a very low crunch game, though, and a lot fluffier than many.
A lack of minis was part of the difficulty I think. We are all used to having a battlemat and minis out so everyone can tell at a glance how close things are. Made a few mistakes in how combat works - only movement provokes an attack of opportunity, for example, and there is no penalty for shooting into a melee.
Although we didn't finish the adventure (I was DMing), I think the four players still had a lot of fun being their dogs. And that's really the point, isn't it?
