The Witness is a 2016 puzzle video game developed and published by Thekla, Inc. Inspired by Myst, the game involves the exploration of an open world island filled with natural and man-made structures. The player progresses by solving puzzles, which are based on interactions with grids presented on panels around the island or paths hidden within the environment. The game provides no direct instructions for how these puzzles are to be solved, requiring the player to identify the meaning of symbols in the puzzles. Wikipedia
