Good, however...

… something really special lacks in this game.
I would suggest opened windows in the background to be transformed into maze obstacles - outstanding way to improve gameplay catchiness
There should be a score board as well
And snake would better consist of circles rather than squares, or make it at least an option

Thats what stops me from playing this game
BTW* if not for your note about youre responsible reading of reviews, I wouldnt have posted it. Nice ;)
