Steer the silkworm using the iPhone's fantastic accelerometer (gyro) so that it can eat the apples before the silkworm gets too long. This game is similar to the classic game of Worm in the sense that the silkworm is not allowed to collide with itself.
However, there the similarities end.
In this twist of the game, you must avoid whirlwinds and electrical fences, get tokens for faster and slower worm speed. Try also to get extra lives in different ways.
Furthermore, you navigate the worm on a three-dimensional sphere.
Also, the player can quickly move the iPhone upwards in order to make the silkworm jump. This can be used to jump over itself or over an electrical fence.
