Nice game and presentation! One suggestion is to have visual indicators on the doors to show which ones are connected.
Thanks, the original design had colours on door pairs but that unfortunately didn't make it into the final game or wasn't as obvious. The entrance/exit doors are always above/below each other though but that doesn't help too much it seems.
Yeah, the colors would have helped a bit. Though it is a minor issue and I quickly got used to the doors after playing a few rounds.
