I cannot say because it is not for me to decide. Let me explain:
The first room is a fan remake of a real existing escape room and it was playable until January 2022. The owners noticed the game on Steam and did not want their puzzles to appear online and asked me to deactivate it. At some point in time, it might get reactivated but it is for the owners to decide on that. Last status from June 2022: the owners still do not know when they will decommission their room so it will take a bit more time to wait for the first room to come back into the game.
