OpalMist drops you behind the dial of a lonely midnight radio. Spin the
weighted tuning knob and feel its inertia carry you across the band while
two live waveforms dance on the scope: your noisy received signal and the
hidden target wave. The closer you slide to the right frequency, the
weaker the static becomes and the clearer the picture grows. Align both
curves, hold them together and capture the station before it drifts back
into the mist. Every new station hides in a narrower slice of the band
behind heavier noise. Spend your coins on six working gear upgrades:
filter the static, calm the knob, widen the lock window and boost every
reward. All sounds are synthesized live, all progress is saved locally.
Tune a fog-night radio, match the waveforms and lock hidden stations.
