By nature of being a jam game, it's definitely a little underbaked, but the art is phenomenal and I can see this evolving into something really cool, even if under a different title.
It stops just short of being an idle game, as the only real mechanic is moving around the dungeon and watching numbers go up or down as battles play out automatically in the background. After your party's health decreases, you run back to town to heal and spend any gold you accumulated, then you can walk a little further into the map before having to run back and heal again. The dungeon layout is static between saves, and its walls are wireframe, so you'll generally be glancing between the minimap and the character portraits to track where you haven't gone yet and how close you are to dying, rather than watching the first-person camera.
