Really original interpretation of Signal. I liked that decoding the transmission isn’t just the story around the game, the signal analysis itself is the puzzle.
The biggest issue for me was onboarding into the first puzzle. I have very little pre-existing knowledge of Fourier analysis, and initially I didn’t have enough information to form a good mental model of what the controls were actually doing. I understood the system through solving it, and once the first stage clicked, the second and third stages were much easier to reason about. I think a little more scaffolding early on could preserve the discovery without making the first step feel quite so opaque.
The audio was the standout for me. The hollow drone, occasional clicks and mechanical sounds, and especially the amount of empty space in the mix fit the setting really well and gave me room to think.
Visually I still like the clean black-and-white language from CRUMBLING CASTLE, although there are enough placeholders here that the game feels like it stopped short of the level of finish it was aiming for.
It’s also quite short, but the central idea is strong enough that I would’ve happily kept going if there were more signals to investigate.
And the final interpretation of the transmission got me. I’m not spoiling it here, but after all that careful analysis, the payoff was absolutely worth it.
