A mystery puzzle game about strange signals from outer space.

You cannot give up now. The signals you picked up almost a year ago are still being reflected off the inner walls of your skull. But all this work in these abandoned nights, and what do you have to show? There has to be some kind of reasonable explanation. They couldn't have been trying to communicate, right? You have to know.

Use your telescope and radio antenna to looks for clues in the skies.

IMPORTANT: The frequency tuner is very sensitive, but it has a margin of error. If you are unable to set it to the exact frequency it will probably still work.

Your state-of-the-art Teletype machine will print out any signal you might receive. Keep track of it all on your cork board.

How to play

Control the game with your mouse. You can play the web embedded version or download the Windows EXE file. On the itch.io version you can play fullscreen in the browser. https://paulmagnus.itch.io/radio-silence

Hints

These are spoilers. Only look at them if you get stuck and want help with progression:

1

!> Interact with the big parabolic antenna and point it to the huge white star. Tune the frequency to 832 Hz on the fancy radio, and press SCAN.

2

!> You will then get a clue about THREE blinking green stars. Look around in the sky. There are three large green blinking starts which stands out from most of the other stars. Investigate all of them with both the Telescope and Antenna.

3

!> Some of the clues you get will be relevant for later. It will all be written on the cork board, so you can reference it later.

4

!> "half the bright star’s frequency" means 832 Hz / 2 = 416 Hz

5

!> Look at the small red star next to the giant white star.

6

!> Look at the directions of the two jets (gamma rays) emitting from the collapsing star. Extrapolate their directions. They are both aiming for a star. One above and one below.

7

!> Listen to the seemingly normal planet (the star below the black hole red star) at 111 Hz to gets the new location.

8

!> Look for the yellow star between the Blue Cross (a cross shape star formation on the night sky) and the Dyson Sphere (it is located at the right of the Blue Cross and left of the Dyson Sphere). Listen to it at 111 Hz.

9

!> Listen to the green blinking planet with the frequency of 111 Hz to get her frequency.

10

!> Point the parabolic antenna at the windows of your house (the house behind you). Listen to it at 777 Hz. Then use your telescope to look at the windows.
