Does the silver block at the end of demo have any use

the-talos-principle

At the end of Talos Principle demo playthrough (22:11), there is a silver block rewarded to the player. Does this one have any use, either in the demo or in the later part of the game?

Best Answer

Those things are also sigils(tetrominos). There are total of 9 silver/gray sigils in game, A-B-C levels have 3 each on their star-doored levels (I really don't know what to call those levels).

Edit: And yes, they are used in some place in game.
