Hey everyone!

Today is a big day for Project ATMOSPHERE — Version 0.4-P6 is finally here!

This update brings Day 25 to its conclusion, pushes the main storyline forward in a major way, and, most importantly, finally gives you a proper introduction to the last new main character joining Project ATMOSPHERE.

Jade.

She is the final new main character to join the game's cast. There won't be any more new main characters after her, so it was especially important for us not to rush her introduction and to give this first meeting all the time and attention it deserved.

But before we get into everything waiting for you in this update, a few important words for those of you who have already played the previous beta versions.

Important Information About Saves

We've put a lot of work into maintaining compatibility with the previous beta versions of this update.

If you've already played them, your existing saves should work and allow you to continue from the middle of Day 25.

That said, we strongly recommend starting Day 25 from the beginning.

Throughout development, we've changed and added various game variables, conditions, and parts of the internal event logic. We've done our best to account for every possible situation with older saves, but we can't completely rule out the possibility of minor inconsistencies.

And, to be honest, there's another reason to start from the beginning.

Day 25 turned out to be huge.

It's long, packed with content and events, and extremely important to the story going forward. Now that the entire day is finally complete, we believe it's best experienced the way it was originally intended — as one big, continuous event.

So, if you have the opportunity, we recommend not jumping into 0.4-P6 halfway through, but instead experiencing Day 25 from the very beginning.

Trust us, it's worth it.

Key Events in Version 0.4-P6

Meet Jade

Here we are.

With Version 0.4-P6, Jade finally makes her proper entrance into the story of Project ATMOSPHERE — the last new main character to join the game.

And I have to admit, this character means a lot to me personally.

A huge amount of time, effort, and, probably most importantly, heart went into creating Jade.

And I'm not just talking about her appearance.

I wanted her to have her own personality, her own way of speaking, her own sense of humor, habits, quirks, and countless little details that gradually make a character stop feeling like just another beautiful image on the screen and start feeling like a real person.

It's been a long time since I've had this much fun writing a new character.

Jade's introduction isn't a small side event. It's a major story event that moves the main plot forward in a meaningful way. That's why we deliberately gave it as much room as it needed.

I didn't want to rush her introduction, cut important moments, or shorten conversations simply to move on to the next event faster.

And the most exciting part is that this is only the beginning.

Jade has enormous potential not only in her relationship with the MC. I'm genuinely excited to see how she'll interact with the rest of the ATMOSPHERE cast.

For example...

Jade and Phoebe meeting for the first time.
Yeah.
What could possibly go wrong?

38 New Music Tracks

The musical side of Project ATMOSPHERE has also received a major expansion with this update — 38 new tracks have been added to the game.

And here I'd like to give a special thank you to our team member Fernandious-art, who put a tremendous amount of work into the music for this update.

Several of the new songs feature original lyrics written by Fernandious-art, with the music itself created using Suno.

Music has always been an important part of Project ATMOSPHERE's identity, so we tried to select and create new tracks specifically around the events, locations, and atmosphere of individual scenes.

We hope you'll notice just how much the new music adds to what's happening on screen while you play.

And once again, a huge thank you to Fernandious-art for all the work!

This Time, the Story Comes First

I've seen quite a few comments saying that the main storyline hasn't moved forward enough in recent updates.

And I think that's a fair criticism.

Lately, we've spent a lot of time exploring side stories and developing individual characters. And I genuinely love what came out of the events with Susan, Monica, Phoebe, Rosa, and the rest of the cast.

But the main story had been waiting for its turn for too long.

So with 0.4-P6, we decided it was finally time to push it forward in a meaningful way.

And there's one thing I want to address directly.

This update does not contain a full-scale LEWD scene like some of our previous major events.

The erotic content hasn't disappeared — there's a scene with Snow White, as well as a lighthearted and playful moment with Phoebe and Rosa.

But this time, I essentially had a choice: cut down Jade's introduction to make room for another major adult scene, or allow her story to take as much time as it genuinely needed.

I chose the story.

Day 25 has already become one of the most eventful days we've ever created for Project ATMOSPHERE.

And I don't want to add explicit scenes simply because it's been a while and we're supposedly "due" for one.

I want those moments to happen when the story, relationships, and characters naturally lead there — not simply because we need to check another box on a content list.

This time, the spotlight belongs to the story and Jade.

And I think once you finish the update, you'll understand why we made that choice.

English & Spanish

All new content in Version 0.4-P6 is fully available in both English and Spanish.

We've also done a substantial revision pass over the game's existing text.

We've fixed numerous issues, revisited some older dialogue, and made a large number of corrections and improvements to the existing translations.

This work will continue in future releases as we gradually bring the writing and localization of Project ATMOSPHERE to the highest level of quality we can achieve.

And with that, Day 25 is finally complete.

It turned out to be enormous — both in terms of the amount of content and the amount of work it required from the entire team.

But more than anything, right now I want to hear what you think about Jade.

We've been working toward her introduction for a very long time. We've put an enormous amount of effort into her personality, her story, her dialogue, and her first meeting with the MC.

And now she's finally part of the world of ATMOSPHERE.

Welcome to ATMOSPHERE, Jade.
