The original Orpheus 0600 release
Orpheus 0600 is the short psychological horror vignette published at reaktori.itch.io/orpheus-0600. Reaktori’s own profile links this exact project, and the release page lists it as released with HTML5 and Windows versions.
The premise is deliberately brief: you are awakened early and expected to continue a mission. The page identifies a science-fiction horror setting and says the game was made in 72 hours for Ludum Dare 60. That describes the production period, not a 72-hour campaign or a measured playtime.
This is an entry reference, not a review of the ending. We have not played through the game, established its full story or verified an achievement or alternate-ending route.
Choose the browser or Windows route
For the browser route, use Run game on the original project page. If you choose the download route, use that page’s current download interface and match the Windows file name. Nisu does not host a copy, repackage the archive or supply an installer.
The page labels the download Name your own price. That is the creator’s distribution interface; this guide did not submit a payment, claim a download or inspect the contents of the Windows archive.
Check the instructions actually shown by the game once it starts. The project description checked here does not document movement keys, save behaviour, a minimum hardware target or a phone control scheme, so none is assumed from the engine name alone.

Read the horror description before starting
The creator describes psychological horror and tags the game atmospheric, creepy, dark, horror and sci-fi. Expect that intended tone rather than an action-game walkthrough or a conventional mission checklist.
Those broad labels are not a complete scene-by-scene content advisory. We have not verified specific jump scares, flashing effects, violence details or accessibility settings. If a particular content concern determines whether you can play, check with the original creator before relying on a spoiler-free summary.
Choose a session where you are comfortable stopping. This guide does not claim that the game autosaves, that a pause control is available or that closing the browser preserves a run. Those are gameplay behaviours we have not tested.
Keep the full team credit with the game
The original release credits Reaktori, Septonks, alberted, hydromethane, Digasnamai, Arda Karakoz and Axel Kulomaa. Reaktori hosts the project page; that does not make the other credited authors disappear.
If a mirror or video uses the title without those original release details, use the project page to confirm the work. A player’s theory or reaction can help you decide whether the tone appeals to you, but it is not a developer explanation of the story or proof of a particular ending.
Quick help
Is Orpheus0600 the same title as Orpheus 0600?
This guide uses the original title Orpheus 0600 and the existing article slug orpheus0600 for the same Reaktori-hosted project.
Is there a native Mac or Linux download?
The checked original page lists an HTML5 build and a Windows archive. It does not list a native Mac or Linux file.
Is this a walkthrough of every ending?
No. It is an original-entry, platform and content reference. Nisu has not completed the game.
