Pretty good. It's fairly deep compared to other "snake" games, and I found myself throughly enjoying the majority of the game, though it's pretty easy. Two things are of mention, the first being the wonderful quotes from confucius, of course. The second one is more of a problem, to me. The tutorial should be built into the first level, Or a stand alone level with an actual level button. I had accidentally skipped the tutorial and when I tried to get back to it by refreshing, I just played the first level, making me figure things out by trial-and-error. Even so, it's a fairly easy and good game.
I dislike when people double-post normally, but I needed to clear it up. I meant to say " something to be said for simplicity" not "something to be side".
I really don't mind this game, and people are giving it too much hardship for what it is. He states that he's not very good with flash in the description, so lower your expectations for a moment. Besides, there is something to be side for simplicity. The only real issues I have with the game are, the block flickering portions move too fast and once you drop your health to zero, you restart the whole game, rather than just the first level, which would make more sense. But as Dtpgg said, it's a good beginner's game. 3-3.5/5 for earnest effort and concept.
