Really fun concept! The movement feels great and the squiggly snake animation and other animations gives the game a lot of charm. I did find it pretty tough - I could usually only make it to around level 3 before getting overwhelmed.
Funny coincidence: I also made a snakelike roguelike for the 7DRL jam called SN@KELIKE. If you enjoyed playing your game, I suspect you might enjoy playing mine too (though it’s also a bit difficult!).
Hope you continue with it post judging. Well done!
