Thank you for making this, this is a super fun idea! I've been looking for 4-player games actually so I can't wait to bring this to my gaming group and we'll get to properly play it probably this wednesday or next thursday.

I just did a solo test run and I can easily see how this is a competitive and tense game, the rules aren't too complex and yet it's not completely luck based, there is also some strategy. The physical assets you've designed so the players will be uncovering the keys is also a pretty and super neat storytelling component!
