In Tow is a fast-paced one-button game.

You score points by collecting chickens. The more chickens you have, the more points you get. To collect chickens, you run forward and jump between platforms. Hold a button to jump higher, press a button while mid-air to jump multiple times. The number of times you can jump depends on the number of chickens you have and you lose one chicken with each additional jump. You lose all your chickens when you hit a bullet.

The game is over when you fall or hit a bullet when you don't have any chicken.
