I really like the art in this game, it fits very well. I do think the camera panning could be better as someone else mentioned. I also thought that the game started a bit too slow, especially with the movement speed. It kind of made me want to stop playing because it was so sluggish. So I would suggest either increasing the base movement speed or reducing the price for it in the shop so you don't have to spend as much time without it. You did a really nice job!
If you have the time, I'd love to hear what you think of my submission. :D
