About this game
The developer's description, from the game's Steam store page.

Open the door and step into someone's memories.
Platonica Space is a sci-fi exploration adventure where you search countless rooms to recover lost memories.
The Story
With Earth made uninhabitable to humans, mankind has spread through the universe. A century has passed since that fateful day...
You suddenly wake up in an unfamiliar room. You step through a door only to find yourself in yet another strange room. This mysterious space is a collection of interconnected rooms, coming one after the other with no exit in sight.
Inside the rooms, you run into other five people who, just like you, also have no idea who they are or how they got here. But as you keep exploring, you realize something: these rooms are built from your memories. Yours and the others'.
Through the memories you find, you will remember who you are. But some of these memories are quite unpleasant. One among you has apparently shot a girl dead. And another boarded a spaceship illegally with a fake ID.
Who are you? Why are you here? And carrying all these questions, how can you escape this seemingly endless collection of rooms?
The Gameplay
Restore Memories by Placing Items
As you explore, you'll find various "memory spots" that allow you to see lost memories. But in order to activate them, you need specific items that you can find throughout the rooms.
These memories are like chapters from a novel with missing pages. Read through them and try to piece together your and the other people's stories.
Whose Memory Is This?
Not all the memories you'll find will be your own. Some will belong to the four other people trapped in this strange space.
Who is the murdered who shot the girl? Who is the stowaway?
Sort through the memories, find out whom they belong to, and the truth will finally come into focus.
A Shifting Space, Changing Every Time You Wake up
Every time you fall asleep and wake up, you'll find that the layout of the rooms and how they connect will change, as will the items and characters you find in them.
You can explore, find items, and uncover memories how many times you like, but remember: no two attempts will be the same.
The Others Trapped Within
Just like you, the others inside this space have lost their memories.
As you help them find out more about themselves, they'll surely repay the favor by giving you hints.
The real question is... should you trust them?
Everyone here has their own forgotten past and their own secrets. Uncovering those may be the key to learning the truth.
