I feel the game was well-executed. It was a smooth experience, did exactly what it aimed to do, with a useful HUD like having radar. It was interesting to see my "tail" in first-person mode as well.
The only flaw is inherent in Snake: it's the same thing over and over again, which gets old quickly. The fact that this version can last even longer before you make a decision makes it all the worse.
As an aside, why is a snake even eating fruit :D
