A ski game

This simple ski game is written in GeoGebra. You can move the skier by dragging the value of the rotation angle. Once you click on the slider, you can also control the skier by using your arrows keys on the keyboard. To start the game, press the "play" icon on the bottom-left. Avoid collisions with the pine trees. Also do not leave the piste. To restart the game from the start, use the Restart button on the bottom-right.
Some artwork for this simple game were used from The Telegraph, Clipart Panda and Wikihow.
