About This Game

You route incoming messages. There is no tutorial and no operator manual.

Wrong choices fail quietly. Patterns emerge from errors, operator notes, and repetition across cycles. That is the game.

Keep the system running. Discover the protocol yourself.

SIGNAL is the quiet, repeating log of a terminal operator.

/// FEATURES

  • Rule inference - no tutorial; discover the protocol through play

  • Loop-based progression - new operators, new dangers, new questions with every cycle

  • CRT terminal aesthetic - entirely drawn in code, zero external art assets

  • Atmospheric sound - terminal feedback, static, interference - not voiced narrative

  • Multiple endings - when and how you close the loop matters

  • 14 Steam achievements - never announced in-game, unlocked in silence
