Nice and simple concept, but it really gets nowhere... If you want to make this a lot more fun, make levels, like getting to level 2 when getting a certain score. With each level it becomes more difficult, and you always start at the beginning of a level, you never start at the beginning. I think that could be a great idea for you to use. 4.5/5 stars for the extreme possibility that this could expand into something really great. :)
