Santa Clause is upset. The landscape around his workshop has changed. Will you help him fix it? 

There are some green glow-in-the-dark trees around the place which guide us. The landscape is snowy, except for one place that has lava. Would you repair it, so that there is snow everywhere? When you press the play button the snowman on the hill melts. Why? When you find the reason and fix it, you can build your own snowman.

Near the church there is a huge snowflake that goes towards the sky, instead of moving from the clouds to the ground. How can we invert its motion?

There is a surprise waiting for you when you finish your missions.

The workshop is conducted in the Greek language.
