I had never seen this type of game before, but a band known as Polyphonic Spree is using a game called Quest for the Rest to promote their new album. When you complete the game you get to hear one of their songs (which was pretty good by the way). The game was created by the makers of Samarost.
The basic idea of the two games is to click around until you can figure out how to achieve the goal on that screen. It’s kind of fun if you have some free time on your hands, but I wouldn’t recommend it for impatient people.
