I'm playing Proteus, an exploration game by Ed Key and David Kanaga.
This is a pure exploration game, with no goals or objectives or guidance. It takes about thirty to sixty minutes to see everything, depending on how fast you travel to the next season. Each time you play the game, the world is semi-randomly generated: the same elements are used and become familiar, but are arranged in a different order. You can save a “postcard” to share your particular level with others. Controls use the WASD keys to move and the mouse to look, and the game exhibits a brisk movement speed (although I would like the have the ability to let the user change the walking pace). The game world features a nice variety of wildlife and wonderful music with accents based on surroundings. You will also experience seasonal and meteorological changes during your time on Proteus. Although there isn’t anything to “do”, Proteus offers a relaxing exploration game with neat things to discover.
