It's just space, literally! "Lunar Mission" https://mazerooms.com/rooms/lunar-mission/ is a very atmospheric quest: everything glows, blinks, like in a real space station. There were four of us, and everyone found a task for themselves. The riddles are non-standard, you really have to think, cooperate. It's cool that there are no banal locks, everything is with technology and mechanics. In places it was really tense - as if the oxygen would really run out!
