cool graphics, but the gameplay is missing something i believe

cool graphics and nice sound effect. But the gameplay was a bit off.

Umm.. so what does the worm do? It just damage till end? 

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! ;)

Cute game! I liked the graphics and sound. I liked the combat, but the pacing was a little slow. 

I won! Hey that was a cute lil game. I'm guessing that you had ambitions but didn't quite finish?
