When I was a kid, we had this awesome snakes gam on our DOS computer. Ever since, I've been trying to find a snakes game that has the same basic rectangular snakes on a rectangular screen, where the levels vary by what obstacles they have on it. Most of them are too graphically fancified and don't have the right feel to the levels, but this one finally does.
If you're looking for something fancy, then this isn't it. But if you're like me, then this is the best you can find.
Pros - Simple to learn, levels increase difficulty by what their layout is, but you can play multiple levels at once instead of having too play the exact same level over and over before moving on. Good level up system for getting three stars in a level.
Cons - Unfortunately, using the touchpad for arrows just isn't as easy as using keyboard keys. The graphics are kind of cheesy too, like a kids game.
