An interesting mechanic to change between the two snakes and to build a more giant snake via the food :)
Maybe you add some sound design to it and give the game some juicier feedback to the player. I struggled a bit to figure out that you have to be on the side of the compartment to build it up. For a solo project, it's a great effort, and you shipped a finished game!
Feel free to have also a look at our submission.
