The graphic is really cute and well done, but there is no game here. There is no challenge or interesting choice to make, except eating a worm with a non-clear effect. Moreover the controls were clunky.
I'm sorry to be so harsh, but I'm assuming you are here to listen an honest opinion for improving.
By the way you have proved yourselves that you know how to program, which is something that most of the people can't do, and you make amazing art too. Now you just need to focus on the game design aspect of the project. Press on! ;)
