Kill the snake, overall nice idea though its clear its a bit unfinished. You probably know this, but health bar really should be there and its a bit of a problem that when you stop moving the character always hits to the left - it could be fixed by setting the direction only on key press event.
The graphics look nice, its probably the best looking snake I've seen in this jam (and there a lot of snake games for some reason xD). But I feel like using pixel art character is not really fitting when used with filtered texture. I would just use NEAREST filter for him, to have it nice and blocky, not blured.
I really like that snake tears into pieces it feels great:P You could expand this by having multiple snakes, and it might be more fitting to have to snake move straight, not in such a very curly way, and maybe faster too - that would enhance the impression that the snake is attacking predator I think. But you would have to test it, maybe im wrong.
Another advice: you might think its unnecessary, but it really good to have any cover art image for your game - it might be even a screenshot. It really draws attention to your game. And you can still do it!
