Celestial Return, a visual novel combining cyberpunk and cosmic horror themes, has received developer updates that significantly improve its performance and visual fidelity on Linux and Steam Deck. Following its initial release, the game presented issues with background video playback and overall performance on these platforms, often limiting the experience to primarily text interaction. Developers issued updates a couple of weeks after the game’s launch, which rectified these problems. The reviewer from Boiling Steam noted, "This review would have been cut a lot shorter if I had not waited a couple of weeks after the release," highlighting the importance of these fixes. Linux and Steam Deck users can now fully experience the game's intended visuals, including background videos and images, enabling full compatibility through Proton.
