The question is not do I have rocks, the question is which of the specimens in my collection are small enough to fit on the gameboard?
I really love this, it's so simple and clean and the questions are well designed to get a vibe from each rock. This will be a great one to be able to pull out at family events. It's clear you put a lot of thought into it!
I ended up with 3 out of 4 planets having no surface, so I had to start getting creative. In the end I discovered one of them was actually a giant biological megastructure made of pure magic plants all the way through, though at first I was tempted to let myself have a re-roll.
The only thing I would change for my personal tastes is to move up the "explore a planet" and "choose a perfect rock" sections by one quarter inch and lighten the printable space background by 20%, to give that room to the map and for making notes on the map. But when you're nitpicking on details that small, you know it's good :)
I'll post a picture on your game page
