Devotion is now available for sale directly from the RedCandle E-Shop (thanks PCGamesN). This game was removed from Steam in 2019 seemingly over political issues between Taiwan and China and late last year GOG.COM quickly backtracked from an announcement it would be sold there. The Windows, macOS, and Linux game is offered in a variety of DRM-free bundles, ranging from just the base game for $16.99 to a package with Detention and Devotion along with both game's soundtracks for $33.56. Here's word on the game itself:

Devotion is a first-person atmospheric horror game depicting the life of a family shadowed by religious belief. Explore a 1980s Taiwan apartment complex lost in time gradually shift into a hellish nightmare. Delve into the vows each member of the family has made, and witness their devotion.
