Good game.
Combining these 2 classic games is a fun concept, and a very original idea. However I do have one complaint, the final boss is too smart. Not only is it faster and longer then the player (towards the snake 'mode') but it was even capable moving itself out of it's own it's own body, meaning you can't trap it. And you can't get a chance to because it always moves faster then you do, it will ALWAYS get you before you could find a way to beat it. There are many hard levels, understandably. Challenge is a good thing, but the AI for the last boss is a cheating bastard! Since the boss is better then you in every sense of the word, there is nothing you can do to win.
