I liked the idea, but it was a little frustrating to me because when I step on the snake's side head, I lose, and it took me many tries to know why I was losing until I noticed it.
I played it alone by the way, at first, it was hard to synchronize the snake's movement with Guido's movement, but I think that's the point. I'll give it a try with a friend.
P.S. This is me playing the game, one eye looking to Guido and the other looking to the snake. XD
