Black & white ski challenge

Description:

Two friends skiing together for fun; what could go wrong? Your brain… because both friends are controlled by you. So pay attention, and learn to distinguish “left and right” from “turn left and turn right”. Think it’s easy? Try this game, and see how big a score you can rack up while controlling two skiers at a time. Of course, you could always pick the easy way out and call a friend for help…
