Coop puzzler. One player plays normal (in daylight, visible), the other players “behind the scenes”.
So you need to help each other, but can’t actually see what the other sees or what they are doing/can do.
Would work best with two separate screens. Perhaps two phones, connected through Wi-Fi. Each phone sees a different part of the same level.
It’s a bit “meh” to just change the view after each turn/move, and ask players to “close their eyes” :p
