Well Dweller Steam is the canonical release for the game on the Steam storefront under AppID 3699590. The store page is live and lists the public release date of September 22, 2026, day-one platforms of Windows 10 and macOS, and a Steam review summary of 97% positive out of 939 user reviews. The Steam Community hub for the same AppID carries the running review feed and player discussion. Other storefronts do not appear on the store page on the research date.
Section 1
Well Dweller Steam listing, AppID and availability
Well Dweller Steam AppID and store page
The canonical Well Dweller Steam listing is the store page at https://store.steampowered.com/app/3699590. That URL carries AppID 3699590 in the path, which is the same AppID referenced by the Steam Community hub. The store page is the source of record for the developer credit (Kyle Thompson), the co-publisher credits (Top Hat Studios Inc. and Doyoyo Games), the public release date (September 22, 2026) and the day-one platform list (Windows 10 and macOS). All other launch-window facts on this site reference that same AppID.
The store page also shows the Steam review summary in the right-hand column: 97% positive out of 939 user reviews. That summary is the Steam-side aggregate and is updated continuously by Steam as new reviews arrive. The Steam Community hub for AppID 3699590 sits alongside the store page and carries the running review feed, screenshots, workshop items and discussion threads.
Other storefronts and SteamDB
The Steam store page is the only storefront the developer and publishers have listed Well Dweller on. The Epic Games Store, GOG, Humble Store and itch.io are not announced as distribution channels on the research date. Anyone looking for the game outside Steam should treat any third-party reseller listing as unverified unless the official publisher confirms it.
A SteamDB dated snapshot is informational only for this launch. SteamDB access returned an HTTP 403 to this research network, so the SteamDB dated snapshot is not used as a fact source for the first launch. The Steam store page and the Steam Community hub carry the same AppID, release date, platform and review facts without the SteamDB dependency.
How to find the canonical listing
The canonical search path on Steam is the store page URL. The developer search page lists Kyle Thompson and shows the Well Dweller listing among his other releases (Crypt Custodian and Islets). The publisher search pages for Top Hat Studios Inc. and Doyoyo Games also return the Well Dweller listing. All three search pages are identity-confirmation only — they confirm attribution but they do not add release-window facts beyond what the store page already says.
The Steam Community hub is reached through the store page's "Community Hub" link and uses the same AppID (3699590). The hub is useful for current player discussion and the running review feed, but it is a community/video source for the purposes of this site and does not add official facts beyond what the store page already publishes.
