Avalanche is a platform game Nitrome released for Miniclip December 22, 2009. Players control a penguin on a sled whose main goal is to outrun an avalanche.
Players can choose to play the game in two different modes. They can play through 15 levels, which require controlling the penguin until it reaches the designated finish line. A player can also play a survival mode, of which the player continues to slide away from the avalanche until it catches up or the player falls off the course.
In survival mode, the penguin is continually going over the same course. The goal of survival mode is to get a high score. The penguin can increase the score by picking up fish.
Every time the penguin goes over the course again, the avalanche is faster, and the enemies and hazards are trickier. The mode ends once the penguin falls down a gap, or is consumed by the snow avalanche. Every time the penguin goes back to play again, their highest score is shown.
Avalanche was the last game in the 2009 winter trilogy.
Unusually, Avalanche's 1.0 icon has a frowning face in the snow. This is possibly a reference to the frowning Nitrome face buttons used in the winter games section of Nitrome.com, since no other winter games would be coming.
