Christmas Forest Escape

Imagine in this game you are a biologist who one day got a phone call from one of the most honored scientist in your country. He wanted to get some information about your researches because he thought he probably found the ingredient of a medicine which could be able to cure the cancer. He invited you to visit his set-out laboratory in the middle of a forest in order to help him finding out some crucial unsolved problem. You packed your luggage immediately and a couple of hours later were already there. You were working when suddenly the electricity went off and all of the machines went dead. You set out to check if the problem derived from the current-generator outside but appallingly you found the entrance of the place locked. Find hidden objects and solve them to get out.
