I think you have a very complete game loop, with the pause page, UI and game over page. The mouse is really cute, and the whole game has the right artwork that puts together the theme. However, it would be better if there is more animation, for example animation when the spider is killed by the cheese ball. Also, the hit box of the flying spider is a lot bigger than it looks like. It was really annoying getting killed while there is still a great gap between my character and the spider.
