Bumping this thread because my wife and I just picked up a Steam download that we’re enjoying, even as much as it is stressing us out! It’s a cooperative game, and I my search shows that at least one other Doper has played and enjoyed it, so I’ll just paste krondys’s description here.
While I can definitely see how it works as a party game, it also goes really well with two people. My wife and I just sat next to each other on our separate computers, so long as one person doesn’t look at the other’s screen. If you’re a romantic couple, the game will definitely help you work on your communication skills.
