Not bad! I think it's pretty basic but for what is intended, a casual mobile game, it does pretty well! Add some sounds, mobile controls, and a little more content to this base and you could have something :)
When you think about things that go on phones *cough* flippy knife *cough* I think basic is probably a good thing to have. Promise there will be more, after all I got a lot of polish and a bunch of bears to implement ^-^
