Sig.Null

About

Sig.Null is a puzzle game built around a simple yet evolving rule set. You manipulate signals and obstacles across grids to reach goals, using a fixed toolkit that never adds new mechanics. The challenge comes from how levels reinterpret the same rules in increasingly clever ways, forcing you to constantly rethink strategies. Each stage feels like a fresh problem to solve without introducing gimmicks. The original Signal version was praised for its tight design, and this expanded remake keeps that focus. Community reviews highlight how the puzzles grow unexpectedly complex while staying fair. Though short, under four hours of gameplay, the progression feels sharp and deliberate. Players note the satisfaction of mastering a system that rewards persistence over pattern recognition. A small but polished experience with a 92% positive rating on Steam.
