Find a way out in Teratomachine: Grey Loop. You will find yourself not just in some room, this is a chain of small rooms that are fixated into the loop. That is, moving along them, you will eventually return to the room with which it all started. You will not find a single door. There will be a window, but it is with a lattice. It would seem that there is no way out, but it is, but it is well disguised. You need to find the same button or lever that will open the invisible door in Teratomachine: Grey Loop. You will need attentiveness and quick wits.
