Run, Santa, run

Hi dear students!

Christmas is coming soon!... but there's a little problem. Santa is fat. You need to get him fit before the Christmas Day. Can you help him run through the winter wonderland?
It's easy:

• Write your name 
• Read the instructions carefully (how to play)
• Study the letter you have to press on your keyboard:

          z- jump           x- roll           c- dive
   
Start and enjoy!
