The Witness packshot image
The yet-completed version of the game allowed played to walk about the island from a first-person perspective. Throughout the island are blue panels that players can interact with; those seen in the demonstration were primarily mazes, requiring players to draw a line from a starting point to a finish point. Other panels showed more complex mazes to be completed. Completing each panel unlocked other areas to explore or panels to complete. Blow has stated that there is more to the game than these mazes, in response to concerns from players; to Blow, "the point is the magic that happens in the player's mind when he understands the subtle things that the mazes are saying - because the mazes aren't just puzzles, they are lines of communication that aggregate, become more complex and eventually say surprising things".
