About this game
There is no voice to guide you. No written explanation. Only cold rooms, symbols, mechanisms, doors, and a presence that seems to record every choice you make.
Welcome to IN & OUT.
Observe before you act
IN & OUT is an immersive first-person puzzle game built around observation, deduction, and visual interpretation.
Each room follows its own internal logic. You will need to study the environment, read the signs, connect the elements, and find the answer that lets you move forward.
The system gives you nothing for free. It waits for you to understand.
Visual puzzles, not instructions
The puzzles rely on symbols, shapes, spatial clues, and logical associations. The game asks you to look closely, form connections, and test your reasoning with care.
This is not about guessing. It is about understanding how the room thinks.
A facility under control
The world of IN & OUT is minimal, technological, and silent. Every space feels like part of a larger protocol: Project ISO.
You move through a cold architecture somewhere between a clinical laboratory and an endless datacenter. The feeling is simple: you are not alone, even when no one is there.
A progression that keeps tightening
Every correct answer opens another space. Every new space introduces a rule, a variation, or a doubt.
The deeper you go, the harder it becomes to separate testing from observation, and observation from obedience. The game does not always tell you why you are here. It lets you discover it through what it asks you to do.
What to expect
Puzzle solving based on observation and deduction.
A cold, silent, controlled atmosphere.
Room-by-room progression through tests and symbols.
An implicit narrative connected to Project ISO.
An experience for players who enjoy searching, thinking, and questioning what they are being asked to do.
The system is waiting
IN & OUT does not only ask you to solve puzzles.
It asks you to prove that you can enter, understand, and get out.

Steam achievements fix — bundle Steamworks bridge, backfill trophies earned befo
Patch notes (annonce Steam / community hub) : Update — Steam achievements now unlock properly Fixed - Achievements were tracked in-game but never sent to Steam, so your Steam profile stayed at 0/15 even after the in-game unlock popped. The Steamworks bridge is now bundled with the game on Windows, macOS and Linux, and every achievement unlocks on Steam the moment you earn it. Already earned achievements - Nothing to replay. Launch the game from Steam once while online: every trophy you already unlocked in-game is pushed to Steam automatically within a few seconds of reaching the main menu.Read full article on Community Announcements (Kasten Studio)
