Holy cow, by far my favorite game of the jam, all categories combined (and I played a lot of them). I completely loose my mind when I saw the cat playing maracas on the corner. And the first time the shopkeeper hear me I FLMAO to death.
The music which stop playing is pure comedic genius and the stealth addition to the snake formula is really clever. (metal snake solid). The art is also top notch.
My only complain is the length of the snake head which is a little misleading, and since the movement is grid based, I think a little subtle grid on the background could really help the player know where he is and where he goes, or maybe adding a subtle texture to the snake parts.
For a first game jam, it's just AWESOME.
