Serpento

Serpento puts a fun spin on the classic Snake game—eating every apple is only half the challenge! Once the board is clear, a door slides open in the wall, and you need to guide your entire tail through it to finish the level. There are 24 stages, from open fields to tight two-tile mazes, plus pits that teleport you across the board and frogs that hop away as you get close. You can choose from three speeds and four control schemes, and your best score is saved for every level.
