I spoke to the developer of the first-person adventure game The Norwood Suite about their plans for Linux.
As it turns out, they already have a Linux build people can directly request but the developer doesn't currently have Linux setup so they've been gathering reports from the community. They said later that it's "only a matter of time" before the Linux build goes live on Steam.
About the game:
The Norwood Suite is a first-person adventure game that takes players to the secluded Hotel Norwood on a simple friendly errand that quickly unfolds into something much more involved. Filled with bizarre characters and curiosities, this mysterious resort is a dense, open-ended world teeming with hidden passages and secrets to discover.
Peer into the lives of the hotel’s guests and staff, explore and interact with surprises behind every door, and piece together a jigsaw narrative that rewards your curiosity. The Norwood Suite features surreal art design, as well as an original atmospheric musical score, composed by Cosmo D, that integrates itself directly into the game world.
