About Sig.NULL

Sig.NULL is a single player casual puzzle game. It was developed by SaintHeiser and was released on September 27, 2016. It received mostly positive reviews from players.

This is a remake and expansion of an earlier PuzzleScript game, Signal. What I thought was so brilliant about the original is that while the rules never change, the level design is such that your ability to fully comprehend and exploit those rules shifts radically over time
