The beta test is coming to an end, and while I still need to finish a few music tracks and sound effects, everything is on track for release!

Communication


I’ve reached out to the press to announce the release date — so it’s now official! 🎉
That said, media coverage has been modest so far (I’m still a pretty small fish 🐟), but if you're part of the press or a journalist, feel free to check out the official press release here:

Zefyr will also be featured in the upcoming "Games Made in France" show next week — stay tuned!

Steam Deck Compatibility – Fully Tested!

Hello everyone! Good news for all Steam Deck owners: I'm happy to report that the game has been fully tested on the Steam Deck, and the results are very promising. 🎉

Overall, the game runs very well on Steam Deck. While there are still one or two minor moments that I’m planning to polish before release, the core gameplay is already very playable and enjoyable.


I - Recommended Settings for Smooth Play


Out of the box, the default graphics settings may be a bit too demanding for the Steam Deck, especially if you're aiming for stable performance and longer battery life. But don’t worry—there’s a setup that works great!

If you're playing in handheld mode, I recommend the following configuration for a balance prioritizing performance over visuals:
  • Graphics Quality: Super Light
  • V-Sync: No
  • Target Fps: 30 FPS
  • Ocean Reflection: No

With these settings, you can expect a battery life between 2 and 3 hours, depending on the levels you're exploring.


II - What about better graphics?


If you're using your Steam Deck plugged in, you can crank up the visuals. The game handles medium settings pretty well, but keep in mind that higher settings may cause the Deck’s fan to kick into overdrive, since the GPU will be working harder.

This is totally normal, but ti might be annoying. Your call!


III - Is it Steam Deck verified?


Not yet—but I’m working on it! While the game doesn't have the official Steam Deck Verified badge just yet, I plan to request it.

So that's it for this time. Thanks a lot for your continuous support!
Have great day!
Peace 😊
