Hey hey! Just had a few runs through, it's a nice and simple concept that plays smoothly on a HTML5 web interface; the artwork is very smooth, appealing and consistent and has a delightful charm to it! The gameplay is fairly simple, but for a game put together in a week, it's good to have a solid loop working, so it's solid!
Music and sound can be tough to get right (I'm personally rubbish at it!), but having a few sound effects at least can give the world and game a bit of life; if you ever get a chance to add to it, some sound effects would greatly improve the experience!
This is a really nice submission and the artwork is solid, so well done! :D
