Review.
Pros:
It's goods and somewhat fun. I like the feature to turn on/off passing through walls, and I've never seen it in another snake game before this one.
Cons/Recommendations:
There's not enough difficulty settings. Your choices are basically super slow or super fast, nothing in between. I think a somewhat faster version of the lowest difficulty would be perfect.
After you die, you have to click the screen to start over.. The problem with that is that you often click and it selects a difficulty.. I think it should say something along the lines of "You lose" and then have a Replay button so you don't have to choose your settings again, which was also a major annoyance.
