After putting up a Beta test, developer Rock Square Thunder who are working on The Lightbringer has now confirmed full official Linux support is happening.
"The Lightbringer is a poetic adventure/puzzle platformer with light combat elements, set in a beautiful world claimed by a vile corruption. Guided by your sister’s spirit, you must prevail where she could not. Cleanse the corruption, become The Lightbringer."
- Old School Adventure
The Lightbringer draws a lot of inspiration from earlier Zelda games, and is all about invoking that feeling of wanting to explore every nook and cranny.
- Semi-isometric Gameplay
With a rotatable camera in an isometric view, you’ll need to look at things from many different angles in order to find solutions to your obstacles. Remember: There’s often more than meets the eye…
- A poetic journey
Your sister’s spirit guides your entire journey, narrating the gameplay entirely in verse.
- Hazardous Dungeons
Explore dark dungeons full of danger. Watch out for traps, secrets and that pesky slime!
On the subject of why, they simply said "After some feedback from the community, we decided to officially support Linux, as we want as many people to experience this poetic journey as possible.". Thanks to this, there's now a direct Linux demo available from the Steam page.
