➢ On GOG, apparently, it was removed on the 14th, and now the game’s link redirects to the catalogue page.
➢ On Itchio, a “We couldn’t find your page” error is loaded when loading the link still found in forums and databases such as on PC Gaming Wiki.
➢ On Kagura Games, it has already been delisted, and with the following message in the game’s store page: “Shady Corner Games has ended its contract with the developer of this game, so it is no longer sold. Customers can still access the downloads if they own the game.”
➢ On Zoom Platform, it was announced it will be delisted on the 21st.
➢ It should still be safe on DLsite and Patreon, as apparently it is self-published there and going by KG and ZP’s messages, self-publishing shouldn’t be a problem.
Regarding Itchio specifically, it was available under the Shady Corner Games’ page, the publisher. If the dev wants to make it available on Itchio again but now self-published, I would imagine it would require him/her to publish under his/her own page.
That seems to make the most sense.
