Well it works
For a game like snake its appeal mainly comes from seeing how far you can get (how big the snake grows) thus you need a simple easy to read system that measures how far one gets in the game like: Levels/# of balls. Old school point system is no good for this type of game, unless it measures time (or something else) to make the score board competitive.
Also this is like crack-head snake. It moves a little fast for the normal snake game player and having to click the mouse to start a game that moves so fast even when there is no consequence for not moving that kind of sucks. Some map changes/ map selection would be nice.
And of course after everything is all set up, presentation.
I'm no expert, i'm just trying to be helpful.
