I have a copper key and a ladder, but not sure where to “use” them. I totally get the Maniac Mansion references and inspiration, and feel that with a bit more time and polish there could be something here. The atmosphere definitely says classic 80’s adventure game, which is right up my alley. A nice twist on the key hidden under the mat, however I would have liked the character to mention there’s nothing under the mat, as it felt like with the bumpy mat I should be able to look under it. Well done.
