Puzzle and adventure fans, your next obsession has officially arrived. Developer Zadbox Entertainment and indie publisher Blue Brain Games (the brilliant minds behind Quern – Undying Thoughts) have officially launched their highly anticipated first-person mystery adventure, Dimhaven – The Lost Source, on Steam.

If you’ve been waiting for a game that respects your intelligence, tests your wits, and wraps it all up in a hauntingly beautiful atmosphere, this is the one to grab this week.

The Mystery of Dimhaven Island

In Dimhaven – The Lost Source, you step into the shoes of Emily Ravenstone as she travels to the remote, mist-shrouded island of Dimhaven to investigate the sudden disappearance of her uncle.

What she finds is a hauntingly nostalgic, abandoned tourist paradise shaped by retro European architecture. It’s a world that feels both familiar and deeply unsettling, filled with interconnected, complex puzzles, hidden mechanisms, and dark secrets waiting to be pieced together.

Why 90,000+ Players Are Already Hooked

The hype for this indie gem is incredibly real. Ahead of its launch, Dimhaven – The Lost Source racked up over 90,000 wishlists globally. Now that it’s finally in the hands of the public, players and content creators alike are pouring in with praise.

While the striking visuals and clever level design are getting plenty of love, one standout mechanic is stealing the spotlight: the unique in-game notebook feature.

Why the Notebook is a Game-Changer: Instead of forcing you to scramble for a real-world pen and paper or desperately trying to memorize complex symbols, Dimhaven equips you with an essential in-game camera and notebook tool. You can capture important details, log physical discoveries, and organize your clues fluidly within the UI. It perfectly simulates the feeling of being a true detective without breaking your immersion.
