It was expected to see some snake games with a "loop" theme but I never expected to play such a fun one!
I'm really not found of snake but your version is a delight. It's easy to understand, harder to master. Sprites look good and the project feels very polished overall.
I enjoyed quite a lot the fact that you have to loop around things to trigger the actions, instead of trying not to bite your own tail. It make the game deeply different from the original snake and make it way more fun imho.
While writing, I'm thinking that it could be a very decent base for a full game. With more levels and mechanics.
Bonus compliment: I love the cover artwork! It's perfect
