Well... it is definitely a snake game.
Not really much to say beyond that. The name really describes the flash enough as it is. I would've liked to see some backgrounds or animation beyond boxes, but its not imperative for a snake game. I ran into one bug where my snake died while being 3 squares away from the wall or its tail. I've only encountered this glitch once, so I'm not going to really say too much bad about it.
If you like Snake games, this is snake in its purest form and therefore, fun but nothing innovative or much beyond a fun time waster.
