I feel mildly ashamed that I let Brothers: A Tale of Two Sons sit in my Steam library for over half a year, fully knowing that it was a very good title that does not consume too much time (it is about 4 hours in length). Brothers is a third-person adventure game developed by Starbreeze Studios; It follows the journey and adventures of two brothers as they struggle to find a cure for their ill father. You can play technically Brothers with either a keyboard or a controller but I would highly recommend using a controller.
Single player co-op is probably the best wording that I can use to describe the gameplay: You control two brothers simultaneously to solve puzzles and progress within the game. The left stick and left trigger are used for one brother, the right stick and right trigger are used for the other. It is a control scheme that feels unique and is used to full advantage narratively to the point where Brothers is probably one of the few games to offer a near perfect marriage between narrative and gameplay.
One of the beautiful aspects about this game is that it tells a story with zero dialog. There is no flavor text, there is really no user interface, and all voices in the game are spoken in a fictitious language (ala Simlish). Aside from 2 or 3 diagrams showing the player how to use the controller, there are no in-game explanations and very little plot exposition; The entire story is dictated through action, body language, and tone of voice.
It is a gorgeous looking game with a stylized cartoon aesthetic, meaning that it probably run on just about anything. I guess if I had any criticisms it would be that the puzzles are satisfying to complete but not entirely that difficult, probably at least partially due to many of the puzzle mechanics being repeated quite often, such as the climbing puzzles, and the lever puzzles, etc. The controls are a bit awkward when the camera shifts around or really, any situation where you are forced to use the left stick to control the brothers on the right side of the screen and visa versa. I did not feel that the this detracted from the game experience, but it is worth noting.
If you can catch it on sale, Brothers literally costs a couple of dollars at most. It is still well worth picking up even at full price.
