This is such a good concept. The musical changes depending on your state were just perfect. It feels like you could do so much with this, especially after seeing that you had even more mechanic ideas up your sleeves with the temperature changes! Love that you added some post mortem style details to your game page too, this kind of info always interests me!
As others have said, definitely push ahead with this! It's a great setup for mechanics to work with when creating puzzles and such a cute character!
