I love a lot about this game! The cards make the use of different geodes feel super approachable. The concept has this delightful Saturday-morning-cartoon feel to it. I like how inviting the story is to exploring the lore behind the geodes while also setting up plenty of smaller-scope stories about life at the camp that players I'm sure would get just as invested in. There's a lot of fun flavor packed into the text of this game.
From a design standpoint, this use of the 3d6D system seems like a really good compass pointing towards designing other games with a central collecting element, whether it be object collecting, monster collecting, or even a grittier survival-type game. I love the direction this pushes 3d6D (showing off the versatility of the system) and will probably use this game as my main jumping off point for exploring using 3d6D in similar ways.
