I love the art. The game loop is simple enough to feel good at it right away but hard enough to keep you entertained. Although it took me a second to figure out what I was supposed to do. I don't think it's very intuitive what 'scale bones' means or how it relates to the numbers above the enemy's heads. But once I figured it out it was very enjoyable! Maybe a 'tutorial' like level with an enemy that doesn't fight back would be beneficial. Great job!
