The theme seems to have potential but after talking to the 2nd person, there is no more content (that I can reach at least), and picking up items I had to click multiple times for it to register. In the game itself, there is nothing really to do, you can't go back down staircases, and like I said after talking to the 2nd person the game is essentially over with no story development or progression. I would recommend adding more to the game and refining mechanics, but overall it seems like a good base for a game. P.S. Adding some audio, even just music, would greatly improve the game's feeling.
