PLAYISM is proud to announce that Mind Diver, the Mystery Adventure game by Indoor Sunglasses is out now on Steam!
To celebrate the launch, a special 15% discount sale will run for two weeks! In addition, we've also put out a brand-new trailer that delves into the truth behind the mysterious case.

Explore a Broken Mind to Solve a Dark Mystery...

As a Mind Diver, explore a young woman's Mind Ocean and repair her damaged memories. Learn about her missing boyfriend, his secrets, and a party hiding something deeply ominous. Listen to conversations from the past and use your own deduction to piece together the course of events.

What is Mind Diving?

Mind Diving is an innovative approach to treating memory impairments, a new technology used to help people restore forgotten memories.

Case Details

Subject: Lina Kukanova
Request: Help with finding Sebastian, who has gone missing
Further Notes: Memories are disintegrating fast. Urgent response required.

Restore Broken Memories and Uncover the Past

Every memory you investigate is missing a key detail. Anything could be the solution. Fill out the correct detail to reveal more of the past.

Every solution is logical, but not obvious. You'll need the right clues to deduce the truth. Listen to private conversations. Inspect small details. Slow down and engage your mind to make the right connections.

Sometimes you can’t see true beauty until it becomes a memory. 

A Tragic Love Story

A couple deeply in love have both broken down. Lina is losing her memories and Sebastian has gone missing. A disturbing party seems to cover up something else. And a dark tragedy is buried deep in Lina's mind.

Discover the Inspirations Behind Mind Diver

Throughout the game, players will encounter references to the titles and films that inspired Mind Diver. Search carefully through memories and items to uncover them.

Keep your eyes peeled for:
『Return of the Obra Dinn』
『Her Story』
『The Case of the Golden Idol』
And more…!

We’re also honored to receive a special comment from Lucas Pope himself, the creator of Return of the Obra Dinn.

“I just played the demo and loved it. The art style and visuals are so good. I can't imagine the hard work that went into capturing and manipulating all that. On top of it all, the mechanics are solid and the mystery setup is extremely compelling. 『Mind Diver』 is absolutely captivating.”
