Very beautiful pixel art. The changing background and the moving curtain looks amazing. I do wish more elements in the room can also have animation. I also noticed the shape of the frame and the layout of the button kind mimics the Tamagotchi. In this way, maybe change the button to look like a Tamagotchi button. Also, maybe the game should give players some visual feedback when they click the button. It can be some star particles that appear, etc. I enjoy the game a lot, it is a very soothing experience.
