I felt pretty stupid at first—I thought you had to click the room the alien was hiding in, but later I realised the text actually says to click the empty rooms instead.
It’s a nice and simple game: click the rooms the aliens aren’t in, but you have to remember where they’re hiding. I really like that you can place the new rooms yourself. You can space them out early on to keep track of everything, but once the grid fills up, it basically turns into Minesweeper.
It’s a very nice short and quick game, especially considering it was made in around 8 hours.
Very well done sgtwombatstudios!
