■A psychological space exploration ADV that regains memories and self through amnesia, countless rooms with no exits, and exploration.
“Platnica Space” is a psychological space exploration adventure where you can regain your memories while exploring countless rooms.
Players wake up to a strange space with no memory, and “place” items to evoke past memories in fragments. You can enjoy a play centered around exploring the truth, with the people you meet, without knowing who they remember. The space, which changes structure with each awakening, and the reset element caused by “drowsiness,” give you a new experience with each exploration.
In a room that I don’t know, I remember myself. Please pay attention to the play experience, created by a calm, sunlight-shining space and the tension that gradually approaches the truth.

■About “Platonica Space”

When I opened the door, I found someone’s memory…
“Platonica Space” explores countless rooms to regain memories
This is a psychological space exploration ADV.




■Story
You wake up in a room that you don’t see at all. It’s a strange space where the rooms continue no matter how far you go. When I opened the door, there was a room next to it, and there was also a room next to it…the exit was nowhere to be found.
You’re missing your memory and meet some people in the room. They all lost their memory, and don’t remember why they were there. As they tour the rooms, they eventually realize that the space is made up of their own memories.
He searches for who he is and why he is there – a way to escape from the endless room.
■Game Features
“Leave” items to regain your memory
You can pick up items in the room. By placing the items you picked up in that room or somewhere in another room, you can regain your memory of “items” and “places.” For example, if you place a knife in the kitchen, you will be able to bring back memories of cooking. Even the same “knife” may allow us to regain another memory in another place.
However, the memories you have regained are not necessarily yours. It also mixes with memories of someone else who is locked in the room. By organizing which memories are who they are, the truth will be gradually unraveled.
“Space” whose structure changes every time you wake up
The structure of the space changes every time you wake up, such as what kind of room is, how the room is connected. Of course, the characters there and the items that are falling are different each time. Go around the room to get items and regain your memories.
“Drowsiness” builds up with each action
With each action, drowsiness builds up, and you will eventually fall asleep. When you wake up from your sleep, you will be in a completely different room. You will also lose all the items you have obtained. Before you fall asleep, you need to take action while thinking about which room you are going to and where to use which items.
Characters you meet in your room
The people you meet in that room are also losing their memory just like you. They may also gradually regain their memories and provide hints. However, don’t believe them too much. By unraveling the past and secrets they have, the truth will gradually be revealed.
