About this game
Premise
The Message from Deep Space is an odyssey of puzzles. Take the role of the mission's Translator, working alongside a scrappy band of scientists, and venture headfirst into the world of deciphering an alien language --- completely from the ground up.
Scenario
Set in 1973, Earth is the recipient of a meteorite that broadcasts radio waves. In the role of the mission's Translator, the player is responsible for designing responses to the meteorite's transmissions, which, if correct, will elicit new messages from the meteorite. Only through this radio wave dialogue will patterns, words, syntax, and meaning all take form, leaving but one question:
What is it the aliens want to say?

Voyager I
Inspired by The Golden Record aboard the Voyager I space probe, The Message from Deep Space takes a realistic approach to deciphering an interstellar message. Beginning with the limited universal constants available to technologically advanced civilizations, the message spans a range of real-world fields of math & science. Decoding the message is tough, but with the support of the game's meticulous linguist, the single-minded computer programmer, and the affable astronomer, it is a challenge fit for anyone with Curiosity and Perseverance.

Update 1.2.0
Hi Translators! The Message from Deep Space has been released for just over 2 weeks now! I first would like to thank you all for the incredible support and love for the game. It makes me really happy to see the fanart, the theories, the discussions, and most of all to see so many of you all have fun with the game. To celebrate, let’s go over some milestones and community accomplishments! 11,000 copies sold! 500 reviews on Steam - "Overwhelmingly Positive"! r/TMFDSgame subredditCommunity made Dictionary viewing tool - Dictionary RendererCommunity made Deep Space Communication Relay - https://dscr.dixonary.co.uk/And let’s cap it off with a fanart roundup! artwork by @kalidelsartwork by Shady Grovesartwork by @kalidelsI wish I could send more of the memes, but ya know, spoilers. Guess you'll just have to join the community Discord :) Thank you all so much! Patch NotesIn this patch, we’ve fixed errors, updated transmissions for clarity and consistency, fixed typos in dialogues and the reference pages, and even added a few new user settings. I’d like to highlight transmission 237, which I updated last patch to no longer include a chemical compound that made little sense (C2) but inadvertently made the transmission nonsensical to solve in a reasonable way. It’s been the biggest issue and I apologize for the trouble. In good news, in this patch it’s fixed! Also, a highly requested feature is here: dictionary entries now display the transmission in which that signal was introduced! For the full list of changes, take a look below! Thanks everyone! ChangesFixed journal entries so they display the Translator’s dictionary words when quickly advanced Dictionary Entries now display the transmission where they were first encounteredBoth Ctrl keys are supported for in-game hotkeysCan disable the screensaver in settingsFixed periodic table issuesBismuth has proper entryElements 87, 88, and 89 added to tableFixed glucose typo in Chemistry -> Common CompoundsFixed a situation where t...Read full article on Community Announcements (Applesinmypants)Patch NotesOfficial
