The reindeer must stay on the clouds at all times. Avoid dark clouds and their raindrops. Your score appears at the top of your screen and when you die your score will appear. The larger coins are 10 points. The little ones are 1 point each. Move with arrow keys. The cloud button on the main screen is your high score. It might be a little bit laggy at the beginning, but it will go away.
I thank MJM3 for the original game!
