I had a really hard time understanding the rules. First I was confused when the rotation of the room took place - when you finish entering the room or when you start exiting it. Then I noticed the lead points and I thought that every time the hero passes through a rotating room it takes a bit from them. Finally I understood that the points are deducted when you place any card by the amount you have rotated it before any placement. And that rotation varies based on if it's clockwise or counterclockwise!
There were times where I just lost even though the monster was still far away but this might be due to small errors (it's a game jam after all). I think the game would be more enjoyable without the lead points, but I felt a sense of accomplishment when I finally did win. Not a bad game.
