This is my most favorite game so far. It reminds me of an old card game "Unlight" where you can flip the cards. I've been wanted to make a game like this. (Well actually I'm trying to make a game like this.)
Ooh, so Unlight has cards where you can see both outcomes on the front side, that's a good way to do it - we've had some problems with people not knowing what's on the other side. Thank you for the kind feedback!
