A new puzzle-exploration game is being developed by Number None Inc. They are promising us that the game is going to be philosophical, quiet and it'll change the way you look at the things. *
The witness is a game that lets you explore a mysterious island and solve puzzles on the way. The puzzles have various difficulty ranges. Completing the simpler ones will give you hints on how to tackle the hardest puzzles.
In The Witness you can go wherever you wish, it's one of the open world games. With this feature the developers are able to include real puzzles that challenge. And in case the puzzle is too hard and you cannot do it, you are able to simply leave it and go somewhere else, even though you can make them as difficult as you want.
The puzzles are really different, some are easy and some are hard, but all of them are interesting, because each puzzle has a bit "communication" inside. And the best part of this game is that you are becoming more creative due to the flow of ideas going in your mind.
