Not really, I guess I didn't express that enough in the description. This is more of a 3D environment showcase than a game.
All the keys are there tho and you can open the safe but I don't really know which of them you are missing but I would guess one is in the secret room, which you can find using a red book on a shelf. And maybe the Earth key which is behind the painting of Prometheus eating his son. The rest of the keys are around the room in plain sight so I would guess you got all of those.
Sorry for the trouble, thanks for playing it anyway.
