Hello, I have two more wallpapers left to collect and I see one of them is in this area and the other is in an area connected to it. Even if I open the game in RPG Maker, I can't figure out how to access this map. Any help or hints would be appreciated, thanks!

Hello! By either turning off the lights completely or keeping the desk lamp on in Alex’s bedroom, a hidden entrance will appear on the [Sunken Docks] map (at the location with the traffic cone effect). Entering it will take you to two different hidden maps.

Thanks so much!
