The codex. You now start with eight runes. The other eight surface one at a time as you go deeper — each a near-twin of one you already know — and each debuts as the round's target, so you meet it before you have to tell it apart. Every rune you've reached is kept in the codex, behind the book on the title screen. Already been deep? Your codex is filled in. A sound of its own. Every sound is new: soft bells and glass, made for this game. A quiet tick now tells you when the timer turns red. iPad, properly. Text and controls are now sized for the bigger screen. Smaller things. Turning haptics off now really turns them off — game over used to buzz anyway. Double-tapping the gear no longer opens and closes Settings. Using SLOW no longer shifts REVEAL across the screen. — Forgebound Labs

New rules past round ten. From round 10, some rules ask for two things at once: "Select all Azure Spire runes." From round 14, some ask for everything but one: "Select everything except Rose." Watch for shades that only look like Rose — those count. The light goes sooner. Past round 15, the runes start to fade earlier and earlier. The deep end finally gets deeper. Accuracy buys survival. Every five perfect reads in a row restores a point of clarity. Retry now brings you back with two. Your read. Game over now shows how you read — precision, recall, and whether you over-select or hesitate. Your lifetime record lives in Settings. Settings. Sound and haptics can be switched off. Remove Ads and Restore Purchases live here too. Fairer rewards. Watching an ad no longer costs you the round it was meant to save, and a revealed signal now appears after the ad closes, not behind it. Rewards appear from round 3, and the tracking question waits until you first reach for one. Smaller things. Resuming a paused round always gives you at least two seconds. SLOWED stays on for the whole round. New players get a short introduction. — Forgebound Labs

First public release. Signal & Noise spent a long time in private builds. This is the one that felt ready. What's in it: — Two kinds of rule and sixteen named runes, recombined every round — A difficulty curve that keeps escalating: decoys that borrow the colors of true signals, hues that shift until they're nearly identical, animations that learn to imitate — Signals that dim as your time runs out, so the board gets harder to read exactly when you can least afford it — Clarity that breaks only when you trust a false signal. A bad read costs points, not your run. — Streak bonuses for perfect reads — Optional rewards, never requirements — reveal a signal, slow the clock, or retry the round that beat you Built for iPhone and iPad. Thanks for reading the signal. ~Forgebound Labs~

Improved text contrast and readability across all screens: the arcane interface is now easier to read at any brightness level. Remove Ads is now accessible from the game over screen. Shop button visibility improved on title screen. Ad infrastructure optimized.
