This clarification by the OP made me change my mind to blue: If people who can't decide for themselves will press their button at random, I'd rather try to press blue.
Fun fact: One of the pledge tiers of the Slay The Spire board game came with a box full of beta art cards.
The beta art is also available within the first game (but I forgot how it's unlocked)
Hi! I wanted to wishlist the game, but just noticed that the store page is unavailable in Germany. You might need to set an age rating to make it available?
