This isn't so much an update as it is a question:
Two backers/potential backers were suggesting that we make the background color gray instead of white. Does that seem to be a good idea? The thinking is it would fit in better with the most common setting/use: a dungeon/cavern. I don't think a medium gray would make it too hard to read anything you may have written on the card using an erase marker.
Thanks again for your support!
