We challenge you to watch video of this game without laughing. 

The game is the brainchild of Bossa Studios, who worked to craft a complete game in 48 hours as an entry into the Global Game Jam 2013. Each year puts forth a theme, and this year’s guiding word was “heartbeat.”

The game gives players control of each of your surgeon’s five fingers and challenges them to complete open-heart surgery on a patient. Hilarity ensues. 

Check out the video below. Make sure to stick around until the doctor starts making comments on his own work. Fair warning: This is a game about surgery on a human, so the visuals are graphic, in a medical science kind of way.
