Congrats to the team on submitting your game!
I'm very bad at Snake-type games, but I'm really interested in their design. I was eager to try yours out! I really liked the idea that there were two types of things that you needed to run over, one for score(hunger) but another that presented an alternate lose condition. That's a neat twist that would be fun to explore in more time than a jam usually allows. And the world/narrative you've built up is delightfully absurd. I put this on the top of my list from the title alone.
I agree with the comment before mine that the movement feels way too jerky. I got used to it after a little bit, but it was still disorienting. And definitely not like a snake. And the game changed dramatically after I realized you can also "block" the rats with your head, effectively making them moving apples that aren't worth points. That's a totally different game, I think. If you work more into this, either explore what being able to eat the rats means, or penalize the player for eating or blocking with your head.
I think the speedup was a neat idea, but didn't end up feeling as good. You lose length so rapidly that it actually benefits you to stay short once you realize you can eat the rats. It'd be more important if the rats could ONLY be blocked by the body.
Overall, very cool entry. Thanks for making this! Keep making games!
