Snake Me app for iPhone and iPad
First of all, its a nice game with beautiful colors, and a very ergonomic interface. Judge by yourself:
The basic rules are very simple, theres a snake which has to eat its feed in order to grow and win points. But you have to be careful: if you hit a wall, you die.
SnakeMe is a completely configurable game: you can choose your levels.
You will find it as your best game in iPhone.
