PC launch is Epic Games Store - not Steam. The gamescom trailer and official pre-registration posts point to Epic and PlayStation Store as the named storefronts. Any "coming to Steam" page is a guess. Beta access has always run through Elementa's own launcher from the official site.

PlatformStatusDetail
Epic Games Store (PC)ConfirmedNamed PC storefront for launch - listing is live as "Coming Soon," wishlistable now.

App Store / Google PlayConfirmedMobile pre-registration is open through the official site flow.
SteamNot announcedNo Steam version has ever been announced. Similar F2P titles sometimes arrive later or never - treat "Steam soon" pages as speculation.
Steam Deck / Linux / MacUnannouncedSame status as Steam - nothing confirmed.
Official launcher (betas)Tests onlyBoth closed betas ran on Elementa's own launcher from the official site. Whether it stays at launch is unconfirmed - do not assume it will.

1What to Do Right Now

2Match Your Situation

Hate the Epic launcher
Pre-reg official + wait
Betas used Elementa's own launcher - watch whether it stays at launch. Do not assume it will, but the official site is the channel that has actually shipped PC builds.
Want it in your Steam library
No confirmed path
Some players plan a non-Steam shortcut later if an official client exists - that is speculation, not a plan you can rely on.
Console player
PS5 is confirmed
PlayStation Store is a named storefront - console players have the clearest path of anyone.
Just want to play ASAP
Official site test + Epic at launch
The Dichotomy: Retrace test (until Oct 10) is the fastest hands-on; Epic is the day-one PC storefront.

Mistakes to Avoid

Summary: Epic for PC at launch, PS5 confirmed, mobile pre-reg open, Steam unannounced. Official site pre-registration covers you regardless of which storefront you end up using.
