The hidden room can only be entered from the 台所 which is at the beginning of the game! そうそう, we need to head all the way back and swap out a batteries along with way.

So once you’ve retrieved the battery, head back up the elevator and towards the コントロールルーム. Ensure you have 15V active on this counter before moving on.

Now head back to the 台所 and ensure you have 20V active on this counter to unlock the Air Flow in the duct behind you on the floor.

Now enter the duct which you should now be able to navigate freely. Travel all the way to the end to finally get to the secret developer room.
