Hi! I'm glad to hear you're enjoying our game!
There are physical copies available, but currently only in limited manner. My co-creator, Jonah, has them printed in small batches and sold at conventions in the UK. They have also been available in limited numbers via the Forbidden Planet store in Glasgow, though I am not sure how many they still have in stock right now.
We haven't printed any larger runs, nor have we sorted out any international shipping. It's uncertain if we will, as the logistics are somewhat complicated and shipping costs are very high.
