Flawed.
Well, I think that it is good to see an attempt at some multiple difficulty levels (though even the difficult difficulty is too easy for me), but I think that there's lots of bugs in this game to be enjoyable.
The scoreboard is broken, and it's not simply too easy as unlike in Snake, but your character doesn't even get any longer! It makes it much too easy, and dull and repetitive (even more so then the original!!!).
If you were to try and fix the scoreboard for this, and if you were to make some more difficulty levels (even harder then the current hardest, or add more walls and a maze, as already suggested).
This sort of game has been done way too many times, and for it to be any good (if at all possible), it would have to be an absoloute BRILLIANT parody of it...
This wasnt even as good as the original, and is therefore, poorer then the very basic Cell phone games. That is just showing how poor this game truly is.
Even more so, this 2 I am giving you is a HUGE overstatement, I just couldn't stand to give such a classic, old submission anything less then a 1 or 0.
Definately needs improvements, but judging by the date of the submission, I doubt that'll ever happen. Which is a shame, because SBC as snake is a pretty classy, fun idea! It was just poorly executed.
